NO!Ok. Call me an idiot
Sort of., but I'm not understanding this.
For instance, with my GK800, if I plug my Sansamp Para
driver into the effects return input, only the master volume
control is usable on the GK. Is there no way to make that
happen with the LMII?
When I put my Sansamp inline now,
there isn't much change in tone and I don't always want to
put everything in the front end of the amp. I thought
changing the effects loop to series put the effects after
the preamp, between the preamp and power amp. Do I be wrong?
I think the problem is you're just oversimplifying what "preamp" means.
The "preamp" is not just that first gain stage. It's the entire section before the power amp including all the tone shaping controls (eq, filters) and whatever other internal "glue" componentry, which all make up the overall "voice" of the amp.
So while it's true the gain control does nothing (since it's bypassed) and only the master affects output level, you're still going through the vast majority of the preamp section because all the tone shaping controls are still in effect... still in the chain... and can still affect gain levels since many are active controls.
So when you plug that sansamp in there, you're "ganging" the LMII tone shaping controls WITH the sansamp's, so it's not just the sansamp you're hearing... it's actually both. Even with the eq set "flat" and the filters off, the LMII still has a "voice" and it will affect how the output sounds. This could very well be a cool way to use this amp and some other box like you're saying... I'm not saying it won't work. I'm just saying it's not a true power amp input because you're getting much more than that.
For a "true" power amp input, you'd have to bybass ALL that stuff, so you'd really have a situation where all the LMII did VERY STRICTLY was amplify what you gave it, and had no tone shaping controls... only maybe an input attenuator... like a Crown power amp.
Some amp heads do have this. The LMII is not one of them.


, Anyway, with the Ashdown my standard settings were Gain at 3 o' clock (yeah very high but it was the only way for it to even register my active Cirrus with a 12v preamp)and master at 12.
