Here is a quandary that I could use some reinforcement info on. I need a smaller amp for smaller gigs. I want the smaller combo to be as versatile as possible, and I have about $400 total to spend. I currently play punk, and we are trying some acoustic punk shows. I also am looking at the possibility of using this amp with acoustic basses, electric uprights or a zeta crossover bass (if I can get my hands on one of them for a good price), or possibly an upright bass. I have also recently purchased a Crate BT50 (50W, 12) to try out for our first acoustic gig, and use GCs 30 day return policy if it doesnt work out for me. Here are the options I am looking at: 1. Either keep the Crate, or upgrade to the Crate BT100-15. I like the sound I am getting out of this amp because it is deep, and really makes that tone knob on my j-bass useful. It also has some cool features, like distortion, and octavizer (the larger one has a limiter), but I also know that these are gimmicky. I love the built in tuner. The only problem is, Im not sold on the reliability/durability/versatility of Crate. 2. Get a different Small combo. The Ashdown electric blue series seems to be my first choice. I have played the 12, and it was not initially as deep as the Crate. I also didnt get a chance to a-b them, or play the Ashdown in studio. It seems to have a lot of the same features, except the tuner. I could really use some in depth reviews of the new EB series from Ashdown, with some discussion of the reliability problems and/or comparisons of the EB to other amps. Is there a pertinent difference between British and Chinese models. (I am also open to other brands). 3. I currently have a Trace Elliot 4x10 combo. The head is a Mark V, and the GP 11. The head looks as though it could be easily removed from the cabinet as it appears to be rackmounted, put in a rack mount case, and used with a 12 or 15cab, but I am not sure that this is possible . I am like this option, because it makes my big combo lighter, and would give me an extension cab. Thanks for reading this. Any opinions, or suggestions, welcome. BTW, I know it boils down to listening to my ear and wallet, but I am wanting to see if there is any options or obstacles that I have not thought about.
