The trick to the overdrive is to pull the notch filter and set it somewhere between 0 and +2. Then set the overdrive knob somewhere between 2 and 4, and the volume around 1/2 to 1.

Could not agree more…………. I’ve had mine since 1992 20 yrs….. Big clean open sound…… not a fan of the over drive but a pedal immediately takes care of that…….. I switched out the red knobs for black ones. now it “looks” good and sounds even better………

Great amp. I’ve had mine at least 15 years and have used Mesa’s, Vox, Rickenbackers and newer Fenders since I got it, but keep coming back to this. More versatile than all the others. Clean sounds are amazing. The overdrive has to be really dialed in to sound good, but with pedals it’s not a big deal. Reverb is my favorite in any amp yet. Tone controls are more responsive than the newer Fenders I’ve used, and the presence/notch filter knob is extremely useful. For a great clean sound with a wide tonal range this is it.
