Hello everyone there are probably a hundred threads simular to this one so I'll apologize in advance but here's my situation, I've been playing for about 4 years and my two main basses are a Mexican precision bass w/ SD quarter pounder and a Warwick rockbass Corvette and for the last 3&1/2 years I've been using a warwick BC150 the 1 15 inch combo and I'm finally tired of not having my own amp when I gig and plugging straight into the pa when I jam with my friends I need something louder, a lot louder there are 3 amps I'm thinking about the ampeg svt 7 pro which my teacher has and I used in lesson and we have a school of rock band we gig with sometimes and I'm fairly familiar with this amp and like the tone but it is a bit bigger than the other two and I'm concerned about reliability, the Aguilar th500 this amp wasnt on my radar until recently when I saw when of my favorite bands Charly Bliss and the bassist was using one and it sounded amazing, gritty and warm but I have not tried this amp myself and probably wont have the opportunity to so theres that, and last but far from least the Mesa subway d-800 this amp was in my local music shop when they realised it a few years ago and I remember it being absolutely breathtaking really great all around and extremely small but it is more expensive from what I can tell,, note that whatever one I buy will be used so reliability is key as for what I play all kinds of rock, classic, indie, lots of punk, post punk that sorts of stuff I like to play a little of everything but with bands that usually what I play. Please help me make the right choice!!
