Randall RD100H Diavlo Guitar Amplifier Head Review

This 100 watt all-tube amp head is built around 12AX7 and 6L6 tubes or EL34 tubes, giving your playing warmth and punch. It has three channels, a boost mode for extra drive, and a speaker emulated XLR direct output for easy recording. A discrete Class A effects loop keeps your pedals sounding full and clear. The 4-function footswitch lets you switch channels and boost with ease, making it perfect for stage or studio use.

6L6 Tubes vs. EL34 Tubes

The Randall RD100H Diavlo Guitar Amplifier Head offers different tonal characteristics depending on whether it uses 6L6 or EL34 power tubes. The 6L6 variant delivers a tight, punchy response with deep lows, clear highs, and plenty of headroom, making it a great choice for modern metal, heavy riffs, and articulate high-gain tones. In contrast, the EL34 variant produces a more midrange-focused sound with a gritty edge, stronger harmonic character, and a classic British-style crunch that works well for hard rock and aggressive lead playing. Both options can deliver powerful distortion, but 6L6 tubes generally emphasize clarity and low-end punch, while EL34 tubes bring more midrange bite and a raw, expressive character. Your choice comes down to whether you prefer a tighter, more defined tone or a more pronounced, cutting rock sound.
