## Description

Large sound stage with excellent detail. Factory selected for low noise and microphonics. Great for both guitar and hi-fi amps.

Review: Marshall DSL1H Tube upgrade - Massive tonal difference across the spectrum i also added a mullard 12at7 in v1 and it smoothed out the gain and fixed the harsh bright treble problems i was having with this amp. I mean wow its a completely different amp now im loving this combination i also just decided to grab the matching 12au7 to compare to the original stock setup. Money well spent!
