Discrete analog design allows this exquisite boost to be balanced and true. Wonderfully transparent and clear, yet powerful. As your amp gain increases to the point of saturation, the Ascend can be used to push your tube amplifiers preamp into overdrive. Reverb tanks are fed beautifully with its strong and concise low end. Component quality is maximized with a "Metal-Can" amplifying transistor as well as metal-film resistors and low-tolerance film capacitors.Because boosts often end up at the front of the signal chain, the Ascend incorporates a J-FET buffer circuit on the input signal. This guarantees better impedence reaction and long cable performance. After all, the Ascend was made for big stages.Features: Bypassable Tone Control Voiced Openly for Guitar & Bass True Bypass Switching Single Point Mounted PCB Flying Leads to Pots and Jacks Neutrik 1/4 inch Signal Jacks Powder-Coated Durable Finish Customer Service Ready to Help Dual Quality-Control Testing Hand Signed and Numbered Hand-made in Minneapolis Mn.
