This is an amazing preamp as it is transparent or apparent, but it never seems to produce an unnatural sound. I had it installed in both my P basses, and just had it professionally removed from my Lakland Glaub (which is for sale). Includes all original parts, packaging and special charger adapter(you will never need to change batteries). Note: chrome finish version. http://www.east-uk.com/index.php/all-products/p-retro.html S-O-L-D No trades for this please.
