Concert Lead issues

[loopyreed]

I just sold my Concert Lead without much knowledge of whether or not it was working properly, so I offered to refund his money if he doesn't think it was in proper working order.  He told me the reverb isn't working - again, I never used the reverb, so I wouldn't know - he says it just feeds back when you turn the knob up. 

I was under the impression that the reverb on a Concert Lead wouldn't work without the footswitch, kinda like the distortion.  Am I right?  Or is the reverb on this thing screwed up? 

Any help is appreciated, if it's messed up I need to give him his money back ASAP.

There are two versions of the Concert Lead. Up to 74 or so the amp had two channels, one with distortion and one with reverb. The later amp had one channel. You should have reverb with no footswitch connected.

I have a concert lead with no working reverb on channel one without the footswitch. I thought it was faulty for quite some time until finding a thread on here where someone mentioned modifying a pair of RCA plugs to trick the footswitch input into thinking it was activated. Haven't played mine in quite some time as it fell into disrepair.. perhaps indicative of previous (sketchy) work on the components? who knows.. but, just my two cents I've seen several concert leads on craigslist and ebay who mention they never got the reverb to work.. coincidentally or not the auctions/ads are never listing it with the footswitch!

Try jumping the two channels together, That is how I got mine to work. The only problem with this method is you will have reverb on all the time. I play music that is slow enough so I have time to turn up/down the presence of the reverb where needed. blah blah.... Anyway from my understanding, the 2 channels are wired parallel. So plug a jumper in to the normal input on 1 and then plug that same jumper into the brite on 2, plug your guitar into the brite on 1. If your reverb does in fact work you should be able to turn the volume up on the reverb. This will also allow you to use both channel at the same time. You will be able to use the normal on channel 2 as an out so you could run another amp if so desired. hope this will help.

on the older model 2 channel silverface:
reverb is on until you ground out the leads(footswitch) to shut it off.  conversly distortion is off until you ground the leads(footswitch).
take a standard RCA cable.  bare the wires(there should be 2) and twist them together.  plug it into the reverb socket(there are 2 there, only one works) to shut the reverb off.  do the same thing with the distortion.  one plug turns on the distortion, the other gives a dB boost.
good luck

I jumped the channels once before selling the amp just to see what would happen - I remember not noticing anything special and I remember the reverb still didn't work.  But thanks for the advice!

Thanks, that's exactly the answer I was looking for.  I went ahead and gave the guy his money back, so it's good to know he was right and I feel better knowing I'm not a junk dealer.
