Pete’s Gear: Hiwatt CP103 and DR103W
Pete Townshend’s use of Hiwatt amplifiers
Hiwatt amplifier details
The stage amplifier Pete Townshend used almost exclusively from 1969 to 1982. He began using the Hiwatts model after using modified Sound City L100 amplifiers with Hiwatt badges, which he used beginning late 1968. The first actual Hiwatt-labeled models featured the same circuit as the CP103 but did not feature the “The Who” branded control panel faceplate. The first CP103 models with “The Who” faceplates appeared in late 1969.
Pete had seven of these amps custom-built for him based on the Hiwatt DR103 design between 1969 and
1976 — in at least three batches — by Dave Reeves of Hylight Electronics with the following factory modifications/differences from the DR103:
- Custom Hiwatt 100 “The Who” control panel.
- middle presence controls .
- Four EL34 power valves.
CP103 amp controls are, from left to right:
- Four inputs
- Four volume controls (one for each input; numbered one through four)
- Master volume
The rear panel contains voltage and impedance selectors and two speaker output jacks. Hiwatt amps of this period, in general, featured Partridge transformers, point-to-point military spec wiring (courtesy of Harry Joyce), bell-like sound and “Spartan” reliability.

Pete plugged these amps into one or two Hiwatt SE4123 4×12 cabinets each (bottoms are occasionally dummy cabinets), loaded with four 50-watt Fane 12″ speakers, specially voiced for increased bass response, or, beginning in 1976, four 50-watt JBL K120 12″ speakers (for extra punch and a cleaner sound). (In 1982, Pete used MESA/Boogie 4×12 cabinets.)

In his standard setup, three amplifiers total are used onstage, two shelved in a custom rack unit (beginning 1972), with one on top of the rack unit. One amplifier is backup. The two amplifiers employed each drive one or both (when not dummies) of the
top two SE1123 4×12s. In this setup, the guitar signal runs from the guitar, to the effect pedal sitting in front of the amplifiers (next to the drumkit), out to a junction box mounted to the side or back of the rack unit, which splits the signal out to the two active amplifiers. Usually, the top left input is used (#1) on both amplifiers.
For effects in his classic setup, through 1978, he used a Univox Super-Fuzz pedal; and from 1979–1985 an MXR Dyna Comp pedal. (For other modifications/variations to his rig during these periods, see the main equipment timeline.)

Three prototype (no “The Who” on control panel) CP103 amps, ca. summer 1969.
Pete’s typical amp settings during 1969–73:
- Vol. 1 (gain):
- Vols. 2–4:
- Master Vol.:
- Vol. 1 (gain):
- Vols. 2–4:
- Master Vol.:
Overall signal (overdrive) is controlled by guitar volume.
1976 settings, as reported by Alan Smith:
“Pete’s amps are custom-made, with no mid-range controls. The treble is usually turned up considerably; the bass just a bit. The volume settings at the beginning of the show are 2/3rds up on the master control and full up on the channel module. By the end of the set, the amps are full on.”
Rack unit timeline
1968–1969:Set up on flat-bottomed chair.
1970–1971:Set up on top of road case, separated by 2×2 blocks of wood.
1972–1975:Custom open rack unit, with one amp set atop unit.
1976–1980:Custom closed shelf unit.
1981–1985:Custom enclosed rack unit.
Three CP103 amps, ca. 1970.
He used the CP103 on stage from early 1970 through the end of the Who’s primary touring career in 1982.

Starting in 1973, Pete used amplifiers similar to the CP103 — the Hiwatt DR103W. These models featured a similar circuit and controls to the CP103, with no “The Who” faceplate. Controls are, from left to right: four inputs, four volume controls (two for “Normal Vols.,” two for “Brilliant Vols.” — a difference from the 1–4-numbered controls of the CP103), Bass, Treble, Master Volume, Standby, and Mains.
In 2000, Hiwatt U.K. issued a signature Pete Townshend model to commemorate this amplifier, which Pete briefly used onstage for early 2006 shows.
Selected quotes from Pete Townshend

From April 1980 issue of Sound International article, courtesy Joe G’s site.
… And then I met this guy who was making amplifiers at the time for a company called Sound City. This is much later, but all I know is once I found the Hiwatt amplifier I stuck with it. I tend to choose a guitar that fits the amp rather than the other way around.
- What Hiwatt set-up do you use?
PT: One amp and two 4 × 12 cabinets. I use a vertical stack but the bottom ones are dead, they’re dummies. I use the bottom ones to stand the top ones on. If they weren’t there I wouldn’t feel right.
- Are the Hiwatts stock?
PT: I’ve tried various speakers in the cabinets but I couldn’t tell you what’s in them now. I don’t know if they’re JBLs or Altecs or what. The ones I use are actually four-input amplifiers; each one with its own volume control and master volume at the end and they’ve only got treble and bass controls. They’re really basic valve amps.
- What settings do you use?
PT: I use the input full up to get the distortion and then turn the guitar down to control the amount of distortion from the guitar. And the master volume about half up. They’re only rated at 95 watts but they’re really good and reliable. I rarely get any trouble on stage.
Guitar, December 1973
I’ve got amps specially made for me by Hi-Watt. They don’t make it any more for the open market, but they do especially for me. They’re incredibly robust, very loud, distorted in the right way, and clean when I want them to be clean. I swap guitars around. I use Gretsches, Gibsons and sometimes Fenders, for their strength. I know people like Ronnie Wood had their guitars especially made for them, custom made. Never been moved that way myself. I can get away with anything because the amps are so good.
Guitar Player, October 1989
I never, ever used a stack with one amplifier until I got into Hiwatts, and I didn’t use Marshalls very long. In fact, I never used Marshall in the beginning at all. I used to use Fenders; I had a Fender Pro and a Fender Vibrasonic and a Fender Bassman top, and I used to drive Marshall 4×12’s with those amplifiers. I thought Marshalls were awful, and I’m afraid I still do, although that’s just a personal opinion. I don’t mean it’s bad stuff: I just mean I didn’t like the sound. And when I heard Hiwatt I was over the moon, because they sounded to me much more like a really good, top-line mid-’60s Fender amp. I still think it’s hard to beat Fender amps; they’re astonishing.
Despite the apparent randomness, Pete Townshend is actually quite selective and specific about his guitars. “In practical terms,” begins Pete, “I look for strength first, and a solid line from tailpiece to headstock — and that all components in that pathway be of high quality and super strength. I’m also very keen on clean, enhanced treble of the Gibson variety, but with no sustain. This more closely approximates the vibration cycle of the acoustic, and suits my rhythm style far better than charged-up, overwound pickups that whine on for hours. However, when I play solos, I like sustain, so a well-matched guitar and amplifier is the key, one in which the treble doesn’t change — up or down — when you change the level of the guitar into the amplifier. All that should change is the amount of sustain, in my opinion. I got a perfect combination for stage work with my Les Paul Deluxes or Schecter teles run into a master-volume Hiwatt.”

Hiwatt CP103 (serial no. 852)
From Colin Tebb:
Re: Hiwatt amp serial no. 852, I used to own it. I obtained it from a music shop in Chelmsford, Essex. I swapped it for a Peavey 20-watt practise amp! It had been in the shop a while and they could not sell it. It was the ’80s and big amps were not popular. They were unaware of what they had.
As a massive Who fan and visitor to the Who exhibition in London where I saw the real thing up close (I’d also helped with the audience overdubs for The Kids are Alright album at DeLane Lea Studios), I guessed it was probably genuine. In addition, a co-band member knew Pete Townshend and wrote to him with a photo. Pete stated he thought is was genuine and said it was probably “borrowed” as they had lost a lot of equipment in that period; however, he did not ask for it back!
I had it for over eight years and gigged with it often using a pair of Hiwatt ex-Moody Blues 4×12s, which I also put in the auction (they did not sell and I later sold them privately). When I bought the amp it had been covered in non-original vinyl covering. I used to work in Southend next to the old Dan Reeves location. A company called Acoustic Sound Services, which manufactured and maintained John Entwistle’s equipment. They re-covered and re-plated the amp for me using original rexine and nameplates by an ex-Hiwatt employee. When I picked the amp up it was sitting on John Entwistle’s bass stack, which was being prepared for a Who tour. The reason I sold it? Well, it was a brilliant amp very loud and quite trebly sounding with a sharp edge/presence and as a Who fan I did a lot of heart-searching before I put it into Christie’s, but it was time for a change of guitar setup and I could not afford to keep it given it was now a valuable item and gigging it was a concern.
Do I regret it? Probably, but it did get me a new guitar and complete amp/speaker setup!
This amp was sold on auction at Christie’s of London, May 1995, and is now display at the Hard Rock Museum in Orlando, Fla., USA.
Hiwatt CP103 (serial no. 853)
A 1970 Hiwatt CP103 amplifier, serial no. 853, owned by Steve, USA:
My good friend and band mate at the time forwarded me the listing for this amp. This was in 1998, before eBay, etc. He found it on a gear site and didn’t have the money for it. I contacted the owner, who told me that he bought it from Arnold & Morgan’s in Dallas, Texas. One of the employees there had been in a band called Kit & the Outlaws who had some local notoriety and opened up for the Who when they first played Dallas. He and Townshend became friends and traded the amp for a vintage guitar.
I decided from the pictures that I had to have a closer look, sent the money ($1,250) to an escrow service and he sent me the amp. It was clearly what he said it was, and sounded fabulous. I’ve had it ever since.
It’s funny, because I was just looking for a Hiwatt, because my former band had a couple of them and I loved them, and you could pick them up in the UK for about £200–300. They were just beginning to get trendy in the U.S., and were selling for about $500–600, so this was double the going rate, and a lot of money for me at the time. But I’ve never regretted it, if only for the look on people’s faces when I turn it on it’s back and show folks the “Who” stencil on the bottom. It really takes your breath away.
It’s missing the back panel, and in the last rehearsal space move I lost the old-style “kettle lead” for the mains power. I’ll probably put in a standard IEC socket so I can use a standard mains lead. I’ve got a nice SE4123 cab for it, serial number 6903. Last time I fired it up, it was still exactly what a Hiwatt should be — crushingly loud, uncolored amplification. Wow.
Many thanks to Steve.
Hiwatt CP103 (serial no. 1095)
A 1971 or 1972 Hiwatt CP103 amplifier, owned by Brad Gray. According to Brad:
Pete had returned the amp to the original Hiwatt company for service and never picked it up. The newer Hiwatt UK sold the head to another collector who had it for a few years. This collector used the new Hiwatt UK to sell it on consignment and I bought it earlier this year (2010).
This amp was used as the reference model for the Signature Series amps that Hiwatt UK has recently released.
The amp still has some Mullard valves in it. It sounds fantastic with a 1969 SG Special plugged in and the volume cranked. Definitely has that Live At Leeds tone.
Excerpt from Hiwatt UK letter regarding sn 1095:
This is to confirm specification /history of the following amplifier:
Hiwatt “Who” Amplifier
CP103 (Model Designation)
Serial Number 1095
The above amplifier has a unique tone /circuit which was specifically designed by David Reeves /Hiwatt for Pete Townshend of “The Who” circa 1971–72.
The above amplifier was purchased from the original Hiwatt amplification company circa 1985, was originally custom built /produced for Pete Townshend /The Who circa 1971–1972.
Many thanks to Brad Gray.
Hiwatt CP103 (no serial)
A Hiwatt CP103 amplifier, owned by Olle Lundin, author of “The Who In Sweden.”
Bought from Justin Harris at Music Ground shop in Denmark Street, London. It seems that the amp has been used with another (HM-hard rock) band, as it is tagged on one side?
We use it as we play it regulary, also in our collection is also an Marshall 8×12 promotional cab. I think they built 4 or 2 promotional cabs, when they did their “Townshend” signature series. These are real 8×12s, in one cab, not parted in two, as the ones that were sold.
