For sale is an Ampeg SVT-DI box. It is a direct box with tube (12AX7). The cool thing is that it includes the power supply in the enclosure. Tubes work better with high voltages and this box includes the power transformer needed to get that voltage (no stupid wall wart) Specs are here http://www.ampeg.com/products.htm?product=96&catid=36 Bought it less than a year ago and used it exclusively at home to record the bass. It gave a nice warm tone. I am moving on to other project and need to sell that baby. Price includes shipping (which is non negligeable as it's heavy due to the power transformer). Won't accept Paypal (tired of their fees!). I'd prefer money order but I am flexible and we can work things out. Thanks!
