I have had a vibrolux without a reverb tank for a while and finally went to my local store and grabbed a new reverb tank. When i installed the tank before a gig, the reverb was quite low, I had it up to 8 just to hear it a little. Any ideas to trouble shoot before i go to rehearsal today (where the amp is kept)? I had the amp recapped a few years ago, and the tech said that teh reverb was weak because the tank was the wrong type, I just never ended up replacing it till now. But the reverb is still weak. any ideas would be greatly appreciated! Thanks!
