Sounds great

madsgc 24.02.2020

Synergy is a great concept and this module sounds awesome. It achieves the expected Diezel sound. High-quality product and study construction.

Boring and flat sound

Alexei F. 23.03.2026

I was expecting a more colorful tone, but it sounds too flat to me. It’s also much quieter than the other modules. I didn’t notice any significant difference between the two channels — they both sound the same. To be honest, my Quad Cortex sounds much better.

Espectacular

R,R. 03.03.2026

Me parece un pre-amo extraordinario. No me esperaba esto. El hi-gain no era lo mío hasta que probé este aparato. Tengo varios módulos y me gustan todos. El BMAN, el OS, el Friedman BE-DLX, el Plexi y, ahora éste. Los módulos que tengo suenan todos de maravilla. Pero, de éste me esperaba un hi-gain pesado y oscuro. Y, no, es un ampli del que se pueden sacar limpios muy bonitos, no cristalinos, pero con mucho cuerpo y muy buen sonido. Pero, cuando lo aprietas, suena muy apretado, sólido, con filo pero sin aristas, contundente. SE hace sentir. Y, el sonido, para mí, es de lo más rockero. Esperaba mucho menos. Podría decir que mi favorito de los 5 que tengo. He probado otros dos, el JPM y el Z-Wreck. Los dos me gustaron, los devolví porque hacían un crock al cambiar de canal con el pedal del Syn 20. Estuve a punto de pedir el Z-Wreck de nuevo. Al final pedí éste y ha superado todas mis expectativas con creces

Bon module dans l'ensemble

Norbert9947 29.12.2021

Si tu cherche un bon son gain et ultra-gain, avec ce module tu seras servi, fidèle à Diezel, par contre pour le son claire passe ton chemin un bon complément avec un module OS par exemple...
