OK. So here are my first impressions of the B-15S vs. B-15T. Skip to the summary if you’re in a hurry. (I'll post pics when I get a chance… and I apologize for the length of what follows, but I’d like your advice on how best to proceed, i.e. what to buy.)
I used a ‘90s MIJ Fender ’75 Jazz RI BTW… sunburst, maple neck w/ pearl inlays and stock (American?) J pickups, VVT controls.
First, the condition of the B-15S ($850):
It’s pretty clean. (And AT LEAST 130lb.) The dolly board has the most tolex damage, there are a few gouges here and there on the cab but nothing major. At least two of the latches have been replaced and they are not a perfect fit and don’t “snap” closed as they should. The jacket on the 4-prong speaker plug is broken but the plug still locks into the jack. Black standby/polarity/power switches, orange lamp/red lamp. (An earlier B-15S?) The tilt-back leg is MIA and the bottom center of the speaker grille is pulled/warped upward slightly. Metal logo is there and one 1-inch long tear in the cloth near the bottom. The Response switch is intermittent when going to the flat setting from the bass setting… if you go all the way to guitar and then back to flat it’s fine. The amp has a LONG grounded AC cord (I’m talking 15ft. or better) and I’m not sure if that is original or not. The speaker is a 2 ohm Eminence Kappa and the amp was set on the 8 ohm setting when I got it. I was told it had a few rattles… one was just an extra speaker mounting nut loose inside, I think a new gasket will solve a few and the others are confined to the tube cage area… not sure if those can be fixed.
How does it sound?!? As I remember reading somewhere… “It’s a big fat “rOund” machine! The fact that it is a tube amp is obvious. Very warm. I can’t really dime it for very long in my basement or the place would fall apart (It’s got volume, I was actually surprised there.) What it does NOT have is headroom… at least what I can hear with my ductwork vibrating in concert with the amp. It even sounds “farty” above 2/3 on the volume for each channel and I’m not sure why?!? I adjusted the impedance switch to the proper 2 ohm setting (nice to have the multiple taps available) and it may have cleaned up a little but all in all I was left scratching my head a little. Maybe I need to get out my tube tester and see if something’s up there. I have an old CTS 8 ohm speaker that I’ll drop in when I get a chance to see what the amp might have sounded like stock. Don’t get me wrong… the amp was a beautiful sounding box that had just enough bite to be authoritative in the blues and classic rock styles, but modern sounding it was not.
Next, the condition of the B-15T ($200):
One latch missing, Replacement Ampeg logo badge (metal w/ italic “Ampeg” – does not match the rounded lower case text on the head – big deal), several of the silver knob faces are MIA… one was loose inside the cab), blue line and graphics on front (older or newer as far as these go?) w/ white signal path chart on top of head, stock (I think?) EV 4 ohm speaker. Tolex is of the nubby variety and is also pretty clean. Four swivel casters attached directly to the cab. It’s about half the size of the larger B-15S and probably less than half the weight. The tone controls are very good and all of the push-pull switches work. One channel and has lot’s of features (master/DI) that can be found elsewhere.
How does it compare/sound?!? Much more modern sounding. I think the tone controls onboard do almost everything that the SVT rocker switches do. It still sounds like an Ampeg if you can believe it. The 100W of output is also very loud. It’s punchy and can be overly bright or overly dark depending on how you dial it in… again, the tone controls make it very versatile. I’m not a slap player, but I was able to manage some slap-tastic squeaks and blurps from it. I felt almost as if it were permitting the Jazz bass to be a jazz more than the B-15S would allow.
Summary: I like them both for what they do and I think I really might get both. Running them with an ABY box would be ideal… they compliment each other very well. (Although, side-by-side they look like a little elephant holding its momma’s tail.)
The B-15S owner has two that are both for sale (apparently both have the 2 ohm Eminence speakers) and he’s willing to let me A/B them and choose which one I’d rather have if I just buy one… and mix/match heads/cabs. If they were $500 each I'd snag 'em both and tweak 'em to taste... but $850 a piece is a little steep to be thinking that way...
I think getting the B-15T is just a no-brainer.
Whaddaya think?!?
