My first post here. I am a true bedroom warrior, and the SV20H/SV212 stack is my first separate head/cab amplifier (and what a great set it is!). I have an issue with my Maxon OD-9 tubescreamer and wonder if I can get some help on this great forum. The OD-9 does not sound well with the SV20H. The sound is murky, and not very focused or well defined, regardless of the settings for drive, tone, and level. Somehow it sounds like there is too much going on, all over the place. I also have a Boss Blues Driver (BD-2) and a JRAD Archer (silver), and they both give a much more focused and well-defined sound, rich in details, together with the SV20H (the price level of Archer is of course different, although I bought it as B-stock at a reasonable price). Anyone that recognizes this problem with Maxon OD-9? - Did I chose the wrong TS? As I understand, the OD-9 is an up-dated version of the more original OD-808. Are the Ibanez-branded pedals better with plexi type amps? - Did I just get a bad ”individual”? - Am I making an unfair comparison? BD-2 and Archer are later products (and the Archer more expensive). Could that the reason for more focus, definition, and clarity? - Or is it so that TS’s does not go together that well with plexi type amps (or the SV20H)? Some background info, on myself and the gear: - I mostly play blues and blues-based rock from the sixties and seventies, but sometimes also newer music, on an HH Les Paul and an HSS Strat. - I am not trying to copy a specific sound, just to get sound that I like. - One favorite is to stack the Archer as a mild boost into the BD-2, with quite some gain. - When I can play loud, I actually prefer the guitar directly into the SV20H, and push the amp with the guitar volume control (particularly for humbuckers). - I usually jump the channels on the SV20H, and play around with the settings. - The rest of the signal chain is a Peterson StroboStomp HD (tuner) first, a Boss Reverb (RV-6) in the FX loop (with short 30 cm/1’ cables), and a Weber MiniMASS 50W (attenuator) between head and cab (also with shortest possible cables).
