I took the fretless to Corner Music over my lunch hour to try out some amps. Corner is a GREAT little shop here in Nashville that caters to all levels from beginner to the seasoned professional! Just cool little shop with a really nice selection of instruments/amps.
First, I tried a ToneHammer 350 with an Aggie 1x12 and it sounded REALLY good! Clean tone with but a bit too "tubby" sounding for my tastes.
Second, I tried the BIG rig...an Ampeg SVT Heritage head with a Heritage 8x10 cab. This combo obviously has earth shattering lows and had a sweet "airy" quality to the mids! Unfortunately as a whole I just couldn't get into it. I had high expectations for it, but was disappointed in it as a whole.
Finally, I went back to the ToneHammer350, but with an Aggie 2x10. All I can say is I'm in love!! Some for of ToneHammer,350 or 500, and a 2x10 is what I will be looking for...and eventually a 4x10 to pair with it for the 6x10 experience! The ToneHammer just has a LOT of tonal variety and I am realizing I like the 'tight/punchiness' that a 10 inch speaker provides!
I also tried a few other basses. A new MIA Fender Jazz, EBMM stingray, Mike Lull 5'er, Brubaker and a Lakland 55-94. They didn't hold a candle to the feel and sound of the Spector with the Alex Webster profile!!
The Spector was the star of the shop! You'd think the customers walking thru the shop had never seen a bass that wasn't a Fender/EBMM/Lakland before! Everyone gawkd at it and complemented me on how beautiful the bass was and the amazing tone that I was getting out of it. Several of them asked if it was mine or the stores...I think they were disappointed when I said it was mine because they wanting to give it a whirl. Some of them were 'stalking' the bass dept waiting for me to put it back on the wall.

If I had more time I would have definitely shared the Spector love and converted a few folks!!
Moral of the story...SPECTOR'S RULE!
