Hi Ken, There are lots of different ways to approach this as has been mentioned. We've struggled with it for a long time and finally achieved the levels we needed as follows: (The guitar has a Martin Thinline gold pickup.) The pickup is connected through a custom-made Zaolla silverline Y-cable (we made it using an insert cable and some adapters) into *two* Stewart UDP-1A Instrument PreAmps. This goes into a Behringer V-VerbPro Processer and from there into the hdsp9632 line-ins through the XLR analog break-out cable. (The V-Verb allows for a lot of fine adjustment on the input, output and block levels.) We've actually had a problem with too much signal on the bass end, but my husband seems to have gotten that under control now. He's getting very satisfactory recording levels now. HTH, Maluvia
