Two Channels with 40 watts of EL34 power, five 12AX7 preamp tubes, housed in a extra deep open-back enclosure and fitted with a Celestion 70/80 speaker. Rich and fat low end, and spongy sweet mids and highs for an overall pleasing tone. Like most Rivera amplifiers, features include two fully independent preamp channels, each with its own distinct voicing (British and American), and footswitchable boosts delivering four easy to dial-up sounds, preamp/power amp patch loop, and line out. This amp sounds much bigger than its size and is affordably priced. Get some "Chub" in your life!

Product ExperienceI own it
Closest StoreKamloops, British Columbia
Owned and used this amp for 17 or 18 years, absolutely amazing sounding and functioning combo. The amount of times to be found inside it?s unassuming looks is insane, having access to blackface and tweed style clean circuits is awesome but then having great rich British style overdrive on the other channel makes these amps perfect. The reverb sounds lush and has very usable tones, the effects loop is great, and having independent footswitching boosts per channel almost makes the two channels seem like four. The only things that aren?t flawless are it?s heavy and on occasion I found the 15 foot fixed wiring footswitch a bit limiting. Since the footswitch is an odd and proprietary cable that can be annoying unless you pickup a cable extension from Rivera. Neither of those two issues merits a lower score in my mind. I?ve loaned this amp out to four people over the years and each of them went and bought their own afterwards, so that says a ton about these things!
