1 TyPierce 4 years ago You guys may already know about this mod, but I just swapped out the stock tank in my Blues Junior for the Ruby reverb tank, and it sounds awesome! I did a bit of horsetrading recently and moved from my Peavey Classic to the Blues Junior. I was running a DigiVerb for reverb with the Peavey, and while I liked the overall tone of the BJr's spring verb better, it was a bit lacking in the depth department. I'm planning to trade up to a DRRI, Pro Reverb or Twin towards the end of this year, but I figured if I could squeeze some more space out of the BJr in the meantime it'd be worth a try. Was it ever! The Ruby tank opened up the reverb in a big way. Deepened it quite a bit and gave it more dimension. To my ear, it seems to have warmed it up a little, too, but since I haven't had a chance to really crank the volume with the new tank yet I can't say that for sure. I've heard (read) a lot of guys complaining that the Jr's reverb is too thin, too shallow, etc. Obviously this tank swap isn't going to put you into 3-knob territory - or even get you in the ballpark of the tube-driven circuits in the Deluxe and Twin - but it does go a long way towards addressing those complaints. A very healthy jump up from the stock sound. The Ruby tank is a direct drop in and couldn't be any simpler to do - four screws, swap over the two RCA cables for send/return and your done. It's not even a one beer job. Mojo currently has them in stock for $25 plus shipping, plus it's completely reversible if it doesn't please your ears. Ruby Tubes Reverb Tank - 3EB2C1B Fender 3-Spring I'll post an update after I can run it through the wringer next week at practice, but initial impressions are more than favorable! Has anyone else done this to their BJr?
