So when I'm using this RV-5 reverb pedal, input A seems to be fuzzy and give out a faint B flat like it's not connecting but i still get sound through it. It also pops and crunches A LOT when you even touch the cord that's plugged into that specific jack. I'm a DIY guy and i can do all the soldering if i know the problem

When you connect your input directly through the power amp input
there is no volume control in the signal route. Only there is a reverb bypass switch which disconnects the reverb.

If it has a effects loop output and input on the p.a. head and a in and out on the reverb effects processor, then yes you can, just run the effects loop output signal into the input on your reverb processor, out of the output back into the input effects loop on the p.a. head, kinda like you would a effects pedal thru the effects loop of a guitar amplifier. hope this helps!

modding the reverb takes some electronics experience...if you know where the reverb circuit is. all you can really do is change the input caps that make the tone bright or dull... larger uf for dull... lower cap values for bright... it's in the signal circuits... dont mess with power caps. The schematic shows op amp into the tank and out of the tank to another op amp...Output of the tank to opamp.. Id double that input cap ( 330 pf ) to see if you get more response into the opamp... then look at the circuit C17-C18/R33-R34

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/lisa_52daba487e5b4d53

Batteries are probably drained... expect maybe four hours on Duracell and Energizer, two hours on Radio Shack batteries. These pedals chew up batteries fast so best to get an adapter... and make sure it is the right one for the pedal.

Did you check the polarity of the adapter? The effect box uses inner pin for negative and outer barrel is positive which is oppsite from most consumer electronics.

There is not a sustainer as such - However you can use the Decay parameter in the reverb module.

1. Set the Module Selector knob to Reverb
2. Choose a reverb type from H = hall, r = Room, s= Spring, A = Arena, t = tiled Room (arena 1 - should do it quite well)
3. Turn the module knob to decay And rotate the value knob until the number 30 shows

Apart from that you may get a bit more sustain from using different Drive modules - the distortion drives such as Ed will give a longer sustain than the clean accoustic drive sounds.
Using heavier gauge strings on your guitar will also give longer sustain but make it a harder to play fast.

Plug your guitar into the input and a cord from one or both outputs to the inputs of whatever you are using. Meant to be run in stereo for best sound. Two guitar amps?

If you have a pedal input, you may be getting FALSE trips of this.

You may have a pedal jack with switch that is marginal.

TRY putting a pedal into the effect pedal input IF your unit has that and SEE if it acts stable.

These jack and jack switch problems are a pain on all these amps... any brand.

A good electronics store should have the part you need. I think its a rubber grommet that your looking for. They are round but become oblong looking once they're in place. Hope this helps.

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.
