Round and round amp settings — Marshall MG30FX
The Ratt guitar tone for “Round and round”, dialed in for a Marshall MG30FX with a Harley Benton Dc 200BK student series. Studio version, Out of the Cellar (1984)
Charvel 'Crossed Swords' Superstrat (Seymour Duncan JB bridge humbucker) into a hot-rodded 100W Marshall Plexi/JCM800 head (modded by Jose Arredondo) with Marshall 4x12 cabinet and studio slapback delay
| Knob | Setting (0–10) |
|---|---|
| Gain | 7 |
| Bass | 4 |
| Mid | 6 |
| Treble | 7 |
| Reverb | 2 |
| Master | 6 |
01Boss NS-2 Noise Suppressor
In front of amp to clamp high-gain hiss between tight rhythm stabs
02Caline Leon Drive
Used as a clean boost to tighten low end and add upper-mid bite into the OD1 channel (HP mode)
03Digital Delay / Slapback
RECOMMENDED — not currently owned; tight studio slapback delay is essential to DeMartini's signature thickness
The MG30FX's OD1 channel delivers the hot-rodded JCM800 character, boosted by the Leon Drive with minimal drive and high level to mirror the Jose Arredondo amp mod tightness. Because the MG30FX has no presence knob and a slightly boxier 10-inch speaker, keep bass pulled back to 4 to prevent mud and push treble to 7 for authentic 80s cut. The Boss CH-1 and Caline Python are bypassed as the signature rhythm tone is dry of chorus/compression.
