My wife heard me make a few comments about needing a 5-string to deal with all of the Bb songs we do at church (the Eb needs to be low - it doesn't sound right on D1) and went to Guitar Center on her own (bless her!) and bought me a GSR205SM. It was OK, the body was beautiful, the frets were finished pretty well, but that Phat II EQ was out of control. So I went back to GC (bless me!) and traded it for the used BTB. Gorgeous bass (will be better when I clean it - you'd think people would clean their gear before trading it in to get a better price!), sounds great, the active EQ is useful (mid-range sweep is a fun new feature to play with), and I got it for almost a straight trade for the GSR205!
I have an Epiphone T bird, bought the badly damaged body complete with neck for £60. Bought some cheap second hand bits n bobs to kit it out and ended up with this.
