hey guys... i'm about to move up to my first 'real' bass... a Spector Euro 5 Neck-Thru... but i dont have a clue how the old Aguilar OBP-1 preamp compares to the new Spector Tone Pump... have any of you had the opportunity to play both?... i would love to try them side by side in person but it seems impossible to find a store within 500 miles that has both... any info or advice would be greatly appreciated.
