Modifications & Improvements Using the Schematic

Once you have the exclusive schematic, the Max 115 becomes a platform for upgrades. Here are two popular, documented mods made possible by the circuit diagram:

Mod 1: The “Grit” Switch (Variable Clipping) On the schematic, locate the gain stage’s feedback loop. By changing a single resistor (e.g., R7 from 10k to 220k) or adding a diode pair in series with a switch, you can introduce soft clipping before the power amp. Many players use this to emulate an overdriven tube bass sound.

Mod 2: Extended Low-End (Deep Switch) The original Max 115 has a natural roll-off below 60Hz to protect the speaker. By tracing the preamp’s coupling capacitors on the schematic, you can increase the value of C5 (usually 100nF) to 470nF or 1µF. This extends the low-end response at the risk of exceeding speaker excursion—use with caution.

Mod 1: External Speaker Jack Disable

The MAX 115’s internal speaker is 8 ohms. Adding an extension cab (minimum 4 ohms) stresses the amp. Cut trace to J5 and add a 4.7 ohm/5W resistor in series with the internal speaker when a jack is inserted (per the unused pads on the PCB).
