This is a good place fo0r a first post
As a bass playing Triwatt builder, I have to agree, a bass amp.
The Triwatt is going to be busy on Guitar.
Beside if I am going to build a bass cab, I want a bass amp.
50 watts that I can put on a 15 or when more is needed use a 2x10 on top of the 1x15. I use 16ohm speakers to give max flexibility.(have to start hunting I still have those hiwatt 12's around somewhere. Fallen in love with Warehouse Guitar Speakers and at this time thats all I am using.
When young I owned and used SA-212 combo (around 1975) and the bass setup SA412, both based on the dr-504 (thought it sucked as a bass amp but great as a rythym amp) traded for an late 60's Ampeg SVT Blue line with a single 15" ext cab. I could almost afford to change the tubes on it now
Although a Garnet BTO downsized would be nice, love the tone hate the ear bleeding.
As for Bass I am hoping he went with a Jazz bass style (my second fav) or music man style (best sounding coils and can be tapped) both must have flat wound strings (my fingers are delicate
) actually I grew up in the 50,60 and 70's and thats the sound of a bass(jamerson) He, JBruce, RGlover and JPJones are the reason I love bass
Favorite bass that I am playing at this time Geddie Lee Japanese Jazz Bass in Black, Ibanez RD900 in Natural, copy of a Gibson Explorer, and my all time fave, My rick
So to wrap up a nice 50 watt or so bass amp would be great, maybe continue the tweed line and go with a bassman style.
