Yes there IS reverb. It DOES work...its just sounds terrible. I think its just a very early digital model of reverb and it just sounds like bad distortion really.

Unless installed as a "repair," there is absolutely no way that the reverb is digital, especially early digital. Limited as it was, digital reverberation in that decade (the 70s) was cumbersome and very costly.

Beyond that, the schematic for your amplifier clearly shows that it employs a reverb tank/pan. So, assuming the amplifier is stock, there must be a reverb tank/pan somewhere.

Is it one of the models that this schematic depicts? http://web.archive.org/web/200808051...erb_studio.pdf

If so, it should have a pan.

Since it is transistor driven, you would want a replacement pan that has higher input impedance (A pan designed to be driven by a reverb transformer won't cut the mustard).

As far as the distortion goes, you could try some mods to the stages that precede the pan in order to alter the gain structure to try and eliminate clipping. Take a look at some modern SS reverb circuits for circuit ideas (like PV amps with SS reverb for example).

That does not look like my model. I might give Danny a call over at Stadel and see if he can' help me out with my reverb problem.

The schematics are available on Standel's website, no need for the Wayback Machine.

So after a lengthy chat with Danny over at Standel I figured out that there should be/is a reverb pan. The pan is located in the chassis apparently. He also helped identify that it is a 100watt Studio. The 8ohm JBL D130F should have the output around 50 watts according to Danny.

Danny also spoke VERY highly of the reverb. So I think I will spend the money to have the reverb fixed.

I have a few amps without verb, or insufficient verb...also some stages will thump and make a reverb tank " sproing " with that thump...I found a wonderful reverb pedal, called ( nicely enough ) The Wet Pedal...simple to use, great sounding, great company, stereo ( or mono ) in and stereo out ( or mono ) and a clean, noise free splitter to two amps...it's none of nthe few pedals nthat I always take to the gig. I know this new post on older subject, but I love this thing so much that I had to chime in. Yes, my Standel's reverb is good ( not super ), but whjy not have an option...this pedal screams " Surf Music " or Paul Horn in the Taj Mahal.
