Re: Bedroom level tube amp hack?
I've been longing for a tube amp but don't want it to just collect dust since I can rarely play loud. I've been using a ZOOM G3Xn in the loop of my katana 100 for effects, but also to step down the volume of the katana for better tones at lower volume. Could I have a similar experience with a low-watts tube amp? (Blackstar HT5-R, VHT SPECIAL 6 ULTRA) or is it possible to add an attenuator and achieve whisper-ish quiet tones? Say an attenuator on a Blackstar HT1-R mini stack or something similar?
Unfortunately, a watt is a watt is a watt and if your speaker is very efficient, the amp will still be VERY loud.
I use two methods for getting valve amps down in level for playing in a small room/low SPL situation:
METHOD 1: ZERO COMPROMISE. This method involves using a Randall iso cab, moving blankets, an Auralex GRAMMA, a hall closet, bungie cords, and some long cables. I drilled two small holes (1" each) in the wall just outside the closet door. When I need a loud guitar part but have to keep it under control I set up my guitar amp at my desk with powered monitors and run long speaker and mic cables from my desk into the closet. Inside the closet I set up my iso cab onto the GRAMMA. The iso cab only attenuates about 25-30dB of level from the amp, so I then wrap moving blankets around it and secure it with bungie cords. This gets the iso cab
waaay down in level; with the closet door closed (and you can close it fully because the wires are not going through or under the door/doorway) the sound coming out of the closet is very low; in my NYC apartment you can barely hear it one room over and can easily watch TV without interruption and more important it doesn't affect my downstairs neighbor!
The mic cable goes into my desk (SSL channel strip) and then into my monitors. You can now get the full sound of your mic'd guitar cabinet at any level you like or through headphones.
NOTE: I typically use a 2W or 5W valve head, but this works for all of my amps which range from 2-100W.
METHOD 2: IMPULSE RESPONSES. This method is much simpler but I don't like the sound of it as much. I run my amp head into a load box and then into an IR generator, then to the powered monitors. The end result is the sound of a mic'd valve amp but you can set the level as you see fit.
I hope this helps.
