Attn: Blue Tube II and Lexicon MPX-100 users

I just got the above new toys and have playing around with them.

I am running the MPX-100 in the Blue Tube’s effects loop with the knobs on the back of the Blue Tube all at 5. On the front of the Blue Tube, channel 2, I have to keep the volume between 1-2 or it distorts, seems to run real hot, so I keep it very low and run the input on the MPX-100 at about 1’oclock. I adjust overall volume with the output control on the MPX-100.

I run stereo line level outs from the Blue Tube into a BBE Sonic Maximizer then into the power amp in of my Nashville 400 and a old polytone amp, so my only real volume adjustment it would seem is the output of the MPX-100 .

Am I on the right track here? Also, if you want to share your reverb/delay settings on your MPX-100 that would be really helpful too.

Thanks

Normally I would use an FX loop inbetween the power amp and the pre amp. I set the loop to maximize the S/N ratio of my FX. If I used the output of my FX as an overall gain control it would defeat the purpose of the loop.

I don't understand where your pre amp's volume control is in your signal chain. If there is only an input level control then a loop would seem useless.

I would set everything to be cranking at peak efficiency and then use the power amp as an overall volume control. The Lexicon stuff can be a little tricky. It really sounds much better when its levels are set properly.

But then again "if it sounds right it is right".

Sam, don't use channel one, its the overdrive channel. Use channel two, its the CLEAN channel.

Kevin-

I am using Channel 2, but even with that I have to keep the pre-amp volume very low. This unit does have the mod in it.

Don’t get me wrong, I love the sound I am getting, nice and rich, and clean at loud volumes, as long as I keep the pre-amp vol low. I am just looking for opinions on my general settings, since this are new pieces of equipment for me.

Bob-

To make a long story short, I am basically set up the way you describe…the levels on the lexicon are set properly using a combination of the pre-amp output and the lex’s input controls. .What’s weird is the fact that I’m running into the power amp in on a Nashville 400, which does not give me an overall volume control on the power amp itself, that is why I use the output control on the lex to set overall volume. Most likely I will transition to a separate power amp and speakers instead of using the combo amp.

Thanks guys…maybe b0b will chime in, I saw some old posts and I think he uses a similar setup.

I've had my best results running the MPX-100 between the preamp and the power amp. I adjust the input level on the MPX so that it just barely goes into the red when I strum the strings hard and my volume pedal is floored. (Set this with the power amp off, of course.)

I run the power amp wide open, and control my volume with the MPX-100's output level control.

I have a Real Tube preamp that I'm not using since I got the Mesa V-Twin, but I ran it the same way. I haven't had good luck with the effects loop on either preamp. I think they design the effects loop for stomp boxes or something. I never got my gain structure right using the effects loop.

Thanks bob, that’s pretty much what I am doing, except I use the effects loop on the pre-amp.

How do you like the Mesa V-Twin in comparison to the TubeWorks pre-amps? What are some of the main differences? Did the Mesa require a mod?

Thanks
