Been doing a bit of speaker and tube tweaking lately, i have my other 2 amps, a CJ11 and Mojave Coyote sounding fantastic, but i think my STR still has room for improvement. It's an original STR, stock except for a GE 6v6 and 5y3. I'm happy as larry with the way it breaks up, and the voicing, the issue i have is with the sound/feel of the cab. I'll explain, the small lightweight pine cab has this tubby sound, kind of like tapping on a tupaware tub on the attack of notes and on muted notes. I hear it in the clips of the STR-tweed too. I think it could sound and feel better if it could be dialed out. Running it through other cabs it goes away, so it seems to be the cab and/or speaker. It's much less noticeable with the natural compression and extra low end thump of my Collings CL, but with my 290 it's quite noticeable. It feels like the amp is almost too transparent (it is very) with not quite enough colouration to cover that sound. (am i making any sense?:NUTS) Here's the thing, i wonder if there's a different speaker there's worth trying, with more of it's own colour, or if it's worth doing something to the cab (adding mass somehow?) to try and dial this out. It has a Mojo BV-30H which is like a G12-H30, it needs at least the low end and volume of that speaker so a greenback is out i think, and a celestion blue won't fit. Maybe a heritage G12-H or a V30? Any tips or tricks for changing the sound of a small, lightweight sounding cab? I know i just made it sound terrible, it's actually a great sounding amp, it has a great direct feel, breaks up in a wondeful way and you can pick out the most balanced chords ever, i just think it could be even better without this plasticky attack thing going on, makes it sound small and it's capable of bigger sounds than that through different cabs. I want to keep it in the small cab though, it's really convinient for the living room and looks cool. Any and all thoughts welcome. Cheers, David.
