Independent shopping perspective
The Korena take
Blackstar’s St. James 100 is a 100W tube combo with two 12-inch speakers and four footswitchable channels. Its valve-mix switch lets you run EL34s, 6L6s, or both together, giving you a selectable power-valve configuration within one amp. A three-position Cut selector addresses the high end, while variable power reduction reaches down to 5%. For direct work, it combines a built-in reactive load and CabRig technology with USB audio and XLR DI outputs. The supplied six-way footcontroller supports a switch-ready stage setup.
Strong match
Who this is for
- Stage rigs needing four footswitchable channels, an adjustable boost, and switchable effects-loop operation.
- Recording or live direct setups using CabRig, the reactive load, USB audio, or XLR DI.
- Players who want to select EL34, 6L6, or blended power-valve operation.
Consider the trade-offs
When to look elsewhere
- Players seeking an amp head rather than a 2x12 combo configuration.
