Does everything I want.
Bruno........... 12.05.2024
I only play high gain music, so i dont use clean channel.

For everything else is just perfect, have plenty of gain on all volumes.
Its very very practical and easy to use. I can play on beadroom levels with good quality or use the line out to an interface and load any IR, so its a king of convenience for any metal and hardcore player.

Ef
The perfect metalamp for playing at home, and more.
Exodus fan 16.08.2025
I use this amp for playing old school thrash and downtuned death metal at home. Don't let the 25 watts fool you : the master volume is at 2 or 3, the power range selector switch is at "low power" and that's enough decibels for me in my living room. The cleans are nice, but for me it's about the distortion. I couldn't get the sound that I wanted through my previous amp (Orange Tiny Terror) but this one does the job easily. Highly recommended!

This thing is a beast!
Dave Fiero 06.01.2025
Unread how a small head amp can bring so much heavyweight sound. My band just used it at a gig and it was perfect.

Absoluter Killer-Amp
phil.anthropic 22.10.2024
Ich könnte nicht glücklicher nicht sein mit diesem Amp!
Hier stimmt alles
- Sehr hohe Verarbeitungsqualität und gute Haptik, man merkt "Made in Germany"
- Viele Features, besonders der Power Attenuator, Line Out und Noise Gate sind sehr nützlich.
- Lead Channel mit viel Gain-Reserven, brachialer Klang.
- Clean Channel ist super flexibel mit tollem Klang, sollte auf jeden Fall nicht übersehen werden
- 25 Watt sind mehr als genug um mit einer Band zu spielen. Im Proberaum geht der Master Volume Regler bei mir nicht über 11 Uhr. Der Amp ist laut!
- Tolles Design

Würde diesen Amp (oder die "normale" 6L6 Version) jedem Empfehlen der High Gain spielt und einen modernen Amp in hoher Qualität sucht. Aber auch darüber hinaus ist es einfach ein toller Röhren-Amp der sich in Sachen Flexibilät nicht verstecken braucht!
