| Marshall valvestate 8080 how to get more reverb
Hi all: I've just bought a secon hand valvestate 8080. It sounds "great" but the reverb was very low comparing to my 8280 valvestate. I changed three resistors in the reverb section and put in the following: R90 and R91: 1M ohm, R92: 100K Ohm. This helped get better/more reverb effect. |

Rather than modifying the circuit, did you consider repairing the existing circuit? perhaps you had a weak drive.

I changed both op amps before and after the reverb tank. It didn't help. I didn't take much time checking the signal i have to say, since i already had these two op amps lying around. tl072 and rc4558. i took a chance But the reverb signal was weak anyhow. Maybe the 5201 didn't switch properly, i don't know, but i'm pleased with the result as it turned out.
