I bought these lamps for a Marshall JMP-1 to replace "Groove Tubes".
According to a lot of information on the internet, I was really looking for an aggressive lamp for the distortion but with very little breath.
I play all kinds of metal, both heavy, death school and death modern, etc ..., I know that the JMP-1 is limited to play the big death metal (But I switch on other pre-amps with a GCX), but the OD2 boosted with a tubescreamer can already get a very aggressive sound.
Well I'm not at all disappointed, I gained grain on the OD2, I have a very hot sound and rock on the OD1, the clean remains clean with good heat and must push hard to have very little natural distortion, and I have no breath at all.
That happiness because they sound much better than the lamps "Groove Tubes".
On the other hand, for the solidity of these lamps I am less optimistic, it is the first time that I buy this mark in lamps and on the 2 which I ordered, I have one which held that 1 hour and she is already dead, that's why I remove 2 stars.
I asked for a product return at Thomann and he sends me a direct and free without having to return the defective lamp, for that Thomann really has an irreproachable service!
