Laney/ADA/and just techie people, talk to me

[Dr.Mavashi]

Ok, here is an idea I have. I am jonesing for ADA MP-1 again for some reason, really wanna give this relic a shot. But! New Iommi's Laney amp has a feature where you can run it just as a poweramp, by pluging in your "remote" preamp straight into the power amp only. First question is how hard, expensive and dagerous it would be for my AOR to be modded for same feature(pre-amp bypass)and then how hard would it to set this signal plit:

A/B/C switch where A:
Just my pedals and effects in to the amp itself.

B)
same guitar and padals into ADA-MP1 into the AOR's poweramp

C)same guitar and padals into ADA-MP1 infront of my AOR

Re: Laney/ADA/and just techie people, talk to me

AORs all have an effects loop. So you'd just need to plug into the effects return to go straight to the poweramp.

So I'd THINK (no experience there° that you'd plug your axe in the AB/Y box, and then run it to the preamp and to the MP1 set into the effects return. I want to try that with my POD 2.0 but my AOR is messed up

Re: Laney/ADA/and just techie people, talk to me

yeah, you can bypass the preamp on pretty much any amp that has an FX loop. just plug in your outboard preamp to the FX return jack.

Re: Laney/ADA/and just techie people, talk to me

Ok, so I don't get than, I thought that effects loop could not handle the type of signal but oh well than. So what is the idea and uniqueness behind Iommi's amp slave/master feature? if I set this chain, my guitar -> tubescreamer->ADAMP1-> FRONT of the AOR do you think it will be just to noisy ??? this for my C option from the initial post. Thanks Dudes

by plugging your MP1 into the front of another amp, youll be stacking the preamps. it'll work and you'll get sound, but it isn't the best idea since you'll be putting the line level output of the preamp into the instrument level input of the AOR.

the slave/master setup is for using other heads as power amps. think of a big wall of marshalls. the amp that the guitar is plugged into is driving a cabinet, but it's also being slaved into other heads that are driving more cabinets. the preamp in the amp that the guitar is plugged into is driving the power sections of the other heads, bypassing their preamps.

in most slave/master setups i've seen, the slave output of one amp plugs into the FX return of the other. an FX loop is basically just a gap between the preamp and power amp, so by plugging an outboard preamp into an FX return on another amp, you won't be hurting anything.

Ok, that's right I totally mixed these things up, retard. Thanks. Ok here is what I have in mind, what do you think guys ???

Guitar -> SD pick up booster -> tubescreamer -> Whah -> chorus/flanger/octave -> A/B/ switch

A - ISP deciminator -> into the High Sensitivity channel

B - ISP deciminator -> ADA MP-1 -> A/B switch A Low Sensitivy channel
B In effects loop


I will have to have a clean patch on ADA for A channel of the second A/B channel so that I do have a clean channel availble, and than of course distorted ADA into naturally clean Low Sensitivity channel of AOR through the B channel of second A/B switch So, channel A of the second A/B will have two patches of ADA. I will have find or build adptors for two inputs and two outputs for the ISP deciminator pedal .... MP-1 has a very versitile chorus of its own so I will turn off the A channel chorus pedal when switching to B channel where ADA chorus will take over.

Re: Laney/ADA/and just techie people, talk to me

If your preamp unit has a switch that switches between "Low/High" or "Amp/Line" or something, try switching it to Line or Low if you run it into the effect return jack. I use my Vox ToneLab in this manner frequently.

Re: Laney/ADA/and just techie people, talk to me

No actually, Laney AOR Pro-Tube 50 watts has Low sensitivity input and High sesitivity input, High is a the crunch one, Low is the clean, there is no switch,
on the back there is just a usual EFX loop.

Re: Laney/ADA/and just techie people, talk to me

I meant for the preamp's output, the switch is usually on the back of the unit. This is because early in an effect chain, the signal has high impedence, and later in an effect chain or in an effect loop, there is less impedence. It is usually not that big of a deal, since many units do not have such a switch, but if it's there, it is worth minding if the signal ever distorts. But there is not real risk of damage.

So what you are saying is that if I will decide to run MP-1 through the effects loop I should drop the impedence to lowes possible on the switch?

by plugging your MP1 into the front of another amp, youll be stacking the preamps. it'll work and you'll get sound, but it isn't the best idea since you'll be putting the line level output of the preamp into the instrument level input of the AOR.

So what is the threat of it? I may burn my pre-amp resistors or something like that ? Now I am thinking of running this into low sensitivity channel, what would you say about thhis approach, is there a way to "filter" line signal of MP-1 into a instrument signal?

Re: Laney/ADA/and just techie people, talk to me

If it's available. If not, then sometimes some tweaking of the parameters is necessary if there is excessive distortion. For the most part there is not much risk with stacking preamps; when this is done, you just have to mind more knobs when tweaking your tone. But overall, what you are planning is fine.
