So today I take my jaguar Squier in to be adjusted and ended up buying the SB4. Honestly I thought I was actually looking at the SB Ray 4. I played it back to back against the Ray34, and through the same amp.
I'm just a hobby player but I can hear.

Honestly the sound between the two were really close. First I didn't like the seal on the Rays neck. Second, I didnt like the Rays colour.
I ended up leaving my Jag for the SB4. It wasn't until I got home that I realized something looked different.
Went to the web and couldn't find the model in SIMM web.
Called Praxis and spoke with Mike he states the SB4is exclusive to GC and MF?
Uh? I men wow! Lucky me. I like the bottom input jack, I didn't like the chrome front panel. I like clean bodies.
I love this thing. It just goes to show if you play any level of bass , buy what your wallet and ears approve of.
Only thing ill get is a white pearloid pick guard and some dome knobs from all parts.

Sorry so long , first post
