I am trying to find an effective non-tone sucking solution to the "need a solo boost" quest. I have tried putting my 10band eq in the llop, did nothng. I tried a BOSS FV-500 which will work, but I can kinda hear a little of the sparkle gone when using the loop. Has anyone succesfully found a mod to make the loop "normal"?, and not affect the tone of the amp at all? I paid good money for the SLO, so I dont want to loose ANYTHING it can do. I'm hearing that pretty much anything put thru the loop will effect the tone, to the critical ear. Can a competent amp tech do anything? I've heard the G System works good, but there has to be a solution to get that loop working , and transparent tone wise. Any suggestions/ideas? Thanks in advance.
