I think you should try ganging before you try tube-swapping (heck it’s free!), just plug your guitar into the R channel, connect the R-output to the L-input, and L-output to the amp. Then, you can crank the R-channel and drop the L-volume to taste. Be careful, you can end up sending more signal than your amp can handle, so start with L-volume pretty low. This way, the L-volume acts like a master volume on a tube amp.

I’d be curious to see what tube-swapping can do, i’ve meant to do it, but never gotten around to it. Since it already had AX7-s in it, that’s as dirty as it’s going to sound, unless someone can recommend a different type of AX7, I don’t think tube swapping will do what you want (but it may do other cool things!).

Hope that helps!

Nope. Tremelo is a volume based effect, so your low end will be fine. I’ve played bass through a Pulsar (I love tremelo, and think it’s underused by bassists) and it sounds great.

That said, tremelo can cause perceived volume loss, regardless of the instrument you’re using, since your volume will drop 1/2 the time, so I like to use a booster afterwards, like the LPB-1, for instance.

But you have to get why this can be a problem. I don’t envy you your job, and I get that you guys aren’t techies, but it seems like the postings here get one of three responses:

a) That question is too easy, do your own research, you’re an idiot. (see above).

b) That question is too hard, contact EH, we can’t possibly help, you’re an idiot.

c) No response at all, which is arguably worse.

My point is that this is the first hit when you google “electro-harmonix technical support”, so acting indignant when people come here expecting technical support won’t hold water, and makes for really bad customer relations.

I don’t want to sound totally negative here, I love these forums, learning about the things people are using the pedals for, pedalboard pics, etc. But, lurking in this corner of the forum makes it clear that this is the last place anyone should go if they expect Help/Technical Questions, and the 1st place they should go if they want to be insulted (and really, I can get insulted online in lots of places…).

Yep, all the ehx tube-pedals come with their own power supply, specifically for those pedals, as far as I can tell.

I have the LPB-2ube, and its been great. I use it to push a Sunn Slave power amp.

As far as tube practice amps go, we seem to be living in a golden age of small, low-wattage tube amps. I have the Vox AC4, and love it, but it seems like every time I turn around, there’s another 1 – 5 watt tube amp being advertised.

There are 12 1/2-steps in an octave (just like moving one fret up on a guitar). So, from your description, I’d expect 24 discrete steps from noon to min.

See, when you’re a professor, they let you have a computer where you can listen to this stuff…

Stay in school, kids :thumb:

Bill, this sounds amazing. Any plans to release this stuff as mp3’s? Itunes or something? It’s too good to exist just on youtube…

Maybe EHX could offer free downloads with purchase? Like how you get the DVD of demos? Just thinkin’

souljah671, the fix might be as simple as tightening the screw between the tubes. You’ll have to take the metal cover off, but nothing more than a screwdriver is required.

I did this to my LPB-2ube and it really cleaned up.
