    Wondering if anyone can tell a few things about this amp. Is this one of Rivera’s designs? Are the control knobs, ceramic tube pods, transformers etc chassis mounted or are they mounted direct to the boards? I have an opportunity to purchase this amp and would greatly appreciated input from anyone who knows this information for sure.

      Very late I know but for reference, they are all chassis mounted.

      I have owned one for several years now and used it often. I also own a Marshal JCM900 half stack and a Mesa Boogie Mark IIB. It’s tough to beat the Marshall but the Twin is easier to move around (casters) and works more gigs for me. I really have enjoyed it.

    i just picked up a 25 year old Fender Red Knob Twin amp and absolutely love it. It’s incredible and versatile. I’m now selling my year old Hot Rod Deluxe lll and my Deville lll . They are just noise compared to this amplifier.

    I finally found a machine good enough for my es 175 at high volumes! This amp is great!

    The amp weighs about a ton.The sound is brutal and (somehow) very interesting. I bought it for gigs (battered,old) but transportation is a disaster.

    It’s very heavy. A freaking boulder. The clean channel is a dream and the dirty channel clips so nicely and it capable of some great overdrive. Mine buzzes when the drive and or treble is set higher than it wants to be. Pretty annoying especially since I ironically used this “Evil Twin” beast in church for 11 years.
    I’ll never sell it although I’m looking at a 68 reissue Deluxe Reverb or a Vox AC 15 at the moment for most gigging which are both about half the weight.

    Actually very heavy, but as my guitar guru said: “when you plug you will say: oh well, God exists! Any other solution may be lighter or more comfortable but it’s not a twin”

    Mine used to be so loud..I couldn’t turn it past 1 on the volume or the neighbors freaked…!
    That’s a 1. So I put in hte garage for about 3 years. Finally I really missed it, I got my forklift out and brought it in the house…jopking…the casters make it ok to move but if you have to lift it…you better be stout! So I plugger it in and it’s got problems. I live about 1 or 2 miles from the ocean and the tubes seem to have green corrosion on the sockets and tube pins. Now it just whispers on 10. It’s so heavy, I’m looking for a mobile amp tech but as we all know…good techs are prima donnas if you aren’t famous. So I”ll get my drummer friend next door and see if he can heft it…he’s a working man. So…I’ll say this, if it is ir was good enough for Tommy Emanuelle it’s good enough for anybody.

    I snatched a ’94 black knob one for 350€ two years ago.
    If you look up some info on this amp, there are some things you will read a lot.

    1: It’s heavy.
    This is true, very damn true. Carrying this around is possible, but it hurts not only your hands because of the strap+weight, but also your legs, because it crashes into them all the time. Casters work but I don’t trust them on uneven floors. Longest I had to carry it was around 100m, I was 17 at that time. It felt like hell, and when I had to carry it back drunk, it felt more like the amp was carrying me. It IS indestructible though. Still using the original valves, no sounds when turning the knobs, no loud idle noise.

    2: It’s loud.
    This is also true. I never needed to use 100W mode (you can switch between 25/100). Clean mode can be tamed if you turn the knob VERY carefully. Mine are a bit stiff, but you can probably change that if you clean the potentiometers. Second channel is a bit harder to set to your desired volume. If one day I am the only person alive in this world, I might be able to turn it up to 4.

    3: Clean channel is good, second channel is ok.
    I would say: Clean channel is great, second channel is fine.
    You can easily get some “Johnny Marr sounds” out of this amp. I have used the amp sims on my GT100 for a while and kind of forgot about my amp. At some point, I randomly decided to play without the effects unit, and I was shocked. Playing on this, if set up right, feels great, and now I don’t practice to get better, but so I can enjoy the sound of my guitar. That said, it is versatile (note the ability to use both channels at the same time), and it CAN sound great, but you can also make this sound like a guitar plugged right into a pair of 10€ desktop speakers.

    Second channel is even more versatile. You can get all kinds of sounds from this, but I rarely turn the gain over 5. Below that, you can get some great “clean-but-not-completely-clean” sounds up to hard rock. If you want a metal sound you should probably get a pedal for that, on most of my guitars I can not distinguish the single notes when I play a chord if I turn it up too much. That said, this is still a Fender, and this probably does much more than most Fenders.

    If you like great price-performance, versatility, durability and don’t mind the weight or reputation, this is a great, great amp.
    Perfect for Volvo drivers, actually.

    Does anyone know how to accurately date these bad boys? The serial numbers don’t correspond with any available Fender resources.

    I used to have a job lugging Fender Twins up two flights of floors – in the Middle of August in Houston.
    Not a job for the faint hearted!!

    Lol at last comment. I’m in Alvin, (30 min) south of Houston, and it’s August. I’ve got one on layaway atm. Got a Custom vibrolux reverb and a broke red knob champ. So I know about the quality of the jacks. Anyone pull half of the power tubes? Does it improve the volume situation? It would be a cheaper retube.

    I have the black knob The Twin it is the answer to all the needs of my amplification ,my amp is carpet with normal Fender metallic silver cloth ! It has channels and reverbs and in/out capabilities due to the addition of both a separate gain channel and a switchable overdrive on the clean, in 1987. It featured a dual output switch, allowing the user to select either 25 watts or 100 watts of output. The Twin was designed for maximum versatility for live or studio use with features like speaker jacks with selectable impedance, Low-z/XLR output, a “Power Amp Thru” feature that bypassed the preamp circuit and a buffered effects loop. Both clean and overdrive channels could be activated simultaneously and reverb could be turned on/off for each channel. Earlier Twin Reverb amps were known among musicians to be best suited for loud, “clean” tones. The “Red Knob Twin” was made until 1994; During 1994 it was slghtly modified and the knobs were changed from red to black, keeping the same
