Reverb not working on studio master - Music

Check the connection to the reverb tank (rectangular box usually sitting on the bottom of the amp). There are a pair wires that connect it to the amp. If wires are connected, and the reverb is not working, you may need to replace the reverb tank.

Here is a link to the schematic drawing
http://www.prowessamplifiers.com/schematics/fender/ps160.pdf

items to check are
1-the footswitch and plug
2-the reverb unit ,usually found at the bottom of the box
3-the reverb unit is plugged in to the amp
4-V6 a 7025 valve
5- the reverb switch is in the on position

Hope this helps

It sounds like you're new to 'professional' mixers. You would NEVER normally use an aux for effects. Any effects will normally be inserted in the sound chain using an insert. You have a pair of group inserts if you are wanting to apply an effect to the output (these are after the mix) and would typically be used for master de-essers or possibly compressor limiters or maybe even an equaliser, it would not be sensible to use an effect like a delay/reverb here.

I would have expected you to be using the group outs for the monitor mixes and am not sure what you may be using them for otherwise. If you used these you would free up 4 of the Aux outs for a 'multi channel' reverb/echos which you could take back into other channels and back into the main mix.

What is it you are tyring to achieve?

Nothing wrong with the amp. Google it- these amps have extremely weak reverb. All of them are the same. It's the one weak point about these amps. And I love mine. I mic it when we gig. Sounds awesome both clean and driven. But you'll have to get a separate reverb pedal if you want "girl crush" or "pipeline" reverb. Don't listen to the above posters. It's the way these amps are.

That's basically normal actually...however it depends on which aux send you're using. If you use aux 1 for the effects, you can use the pre/post switch on the master aux 1 send to switch it to pst fader....now your mute switch should kill the effects as well. Aux 2 is good to use for monitors where you don't need to return them to the mixer.

There are only TWO op-amps and the tank involved with the reverb. Both of those are in one IC chip labeled "U2". It is a TL072.

Pin 1 of that chip is the output to the tank and pin 7 is the inout of the reverb control pot that then goes into the power amp.

They resistively mix the delayed reverb signal with the straight signal at the input of the power amp.

I assume you have turned up the reverb control which is just a volume control for the signal going through the tank.

There are so few parts involved with this that a failure is really rare.

I highly doubt the reverb pan is dead, there are TL072 opamps on the input and output of the Reverb pan. Check those out. You can get the schematic from fenders website here. U6A and U6B are what you are looking for.

Here is an article that might help:http://www.guitarplayer.com/article/reverb-troubleshooting/jun-09/97165 Here is the schematic:http://www.fender.com/support/amp_schematics/pdfs/Hot_Rod_DeVille_Schematic.pdf Check to see if someone hasn't reversed the input and output cables at the reverb tank. Then troubleshoot the reverb section .

Check the input RCA plug going into the reverb tank (silver box with two wires connected to it). Make sure the amp is off when you do this. Sounds like the output is working fine if hitting the amp does it.
