Description

M-PRE produces traditional British rock and metal sounds. The card allows wiring as a dual-volume preamp capturing the plexi vibe, or as a master-volume Marshall 800-style preamp for 1970s-era distortion. A modern update of these circuits allows much more dynamic tone control. Two 12A_7s allow tonal diversity. Local supply decoupling is included.

Use M-PRE as the distortion channel along with our F-PRE Fender-Style Preamp Kit as a clean channel for the highly sought after Fender-clean plus Marshall-crunch tone combo. Modern shredders can use M-PRE as the rhythm channel combined with our Z-PRE High-Gain Preamp Kit as the lead channel.

The board has silk-screening on both sides which allows you to stuff the components appropriately for INTERNAL or EXTERNAL TUBES. For INTERNAL, all the components are on the same side of the board; for EXTERNAL the components are on the opposite side from the tube sockets.

Controls:
• Level-A / Gain
• Level-B / Volume
• Treble
• Mid
• Bass

Power requirements: 12V-300mA; 320V-4mA

Use our PSU-PRE Preamp Power Supply Kit or similar to build a stand-alone preamp.

Combine with our AMP-25 to build an integrated amp.
