I am thinking of getting a more powerufl bass amp. I have only been playing 6 months and the only amp I have is a cheap 15 watt practice amp. The Tech 21 Landmark 60 (60 watt) caught my eye but when I do get into a band (hopefully some time within the next 6 months) then I will need more power than that (won't I). However Tech 21 really appeal to me since thye are renound for quality and great tone. Would it be sensible to get this Tech 21 amp and then when I do get in a band I purchase a 100 watt (or so) bass extension cabinet?? So I get the good tone of the Landmark 60 and the added power of the cab. Also, does anyone know where I can find any more info on things like Amps, pre-amps, power amps, heads, cabinets etc... since it often all goes over my head.
