User upgradeable op-amp
Although supplied with the well-respected TI 4558 dual op-amp chip if you’re lucky enough to have a vintage chip, or just want to try something different out, you can easily swap over. Turned pin chip sockets offer improved pin grip that wont wear out even after hundreds of swaps.
NOS Germanium diodes
Genuine NOS (New-and-unused Old Stock) Germanium diodes sourced from Ukraine. Carefully selected and arranged in an asymmetric configuration to give you a sweet and clean drive you wont find with any modern equivalent. Supplies of these diodes are very limited and once they’re gone they’re gone forever.
- SI : Symmetric Silicon. The classic ‘screamer sound.
- LED : Symmetric red LED’s. A bigger, slightly warmer, more open sound.
- MOS : Asymmetric MOSFET. A tighter, more aggressive sound with rich harmonics.
- GE : Asymmetric Germanium. Specially selected NOS diodes have a cleaner, smoother sound with a touch of bite.
- Hi gain switch : Boosts the dirt right at the front end giving a more full-range boost than the usual tube screamer.
- Bright switch : Reduces the usual tube screamer high-frequency roll-off allowing just a touch more brightness.
