Hello, folks. I'm planning to purchase a new Shuttle combo. I'm not sure at this point which one would be better for my purposes. I'm living in university housing (a small apartment). I want to have a compact, portable amp that can sound good at low volumes as well as have versatility for jam sessions (a wide variety of jazz styles including fusion). I tried the GB Shuttle 3.0 10T, which seemed nearly perfect for my home practice purposes (compact and excellent tone) but there seemed to be a bit of low end roll-off on the B-string notes. Overall it seemed great for low volume practice as well as for playing in a jazz combo. I compared the Shuttle 10T with a SWR WorkingPro 12, and I noticed that the low-B frequencies seemed better articulated on the SWR. However, I liked the overall tone and portability of the Shuttle better. I use a Peavey Cirrus fretless 5 (active). What I haven't been able to try is the 6.0 12T. I'd bet that combo would capture a larger frequency range, and the B-string tones would be fully articulated through the 12" speaker. Furthermore, with the added preamp tube, I'd probably be able to warm up the tone for even more sonic versatility. But I wonder if the added power of the 6.0 head and increased frequency range of that 12" speaker would be excessive in a quiet apartment situation. I needn't be whisper quiet during practice or jam sessions...playing through an amp at moderate converational volumes is fine before 10pm. My main concern is the appropriateness at low volume...the 10T would certainly work in my apartment. Please advise.
