Hey guys and girls.

Well a couple of months ago i picked up a old amp head for free. It has been sitting in my room doing nothing until i thought that maybe as i have a lot of spare time on my hands I should customise it.

Now im not talking anything really serious as this will be my first amp customisation but just a few things to get me started and to have a good laugh.

The amp in question. 'FAL Phase Fifty'


Its insides (sorry for poor quality pictures.)






What I have in mind is to put a light distortion or overdrive in there. I also need to wire it so that it could be connected to a cab becuase its output is not jack plugs but the old speaker wires sites. I also might need to change the pots as there are old and also some have been changed already.

Any other pictures or infomation I can give you please ask for, I just want your opinoins and what do to and then I will give it a go.

your first mod should be to swap out the speaker jacks for the 1/4 inch output.

As far as overdrive stuff, im not sure.

i cant tell the pictures are really blurry, but is it tube or ss?

Looks like a solid state, and rather than modifying the circuit for overdrive or distortion, it'd be alot easier to essentially make a pedal, and then mount it in your chassis, connecting it to your input jack(s).

its ss and greenbox thats roughly what i had planned.

Just look at any tone stack/eq pedal, and then model it at the input stage.

or dude you could mount the eq just before the output and have a post amp eq

you may aswell have a switch for flicking between pre-amp and post-amp stages, as far as using the insides of a overdrive pedal into the master outs is an ok idea, but you'll have to make a resistance pad to power it from the transformer. I personally think you should leave it the way it is, cos its quite a nice amp and probably has a certain sound from its era that would be hard to re-create these days. Buy a practice amp and mod that first so you don't screw it up!
For wiring up a EQ box is not a good idea, because you'll be drawing too much power from the transformer and you probably won't fit it in the enclosure, i'd suggest making your own rack, and having a 32 band stereo EQ box in the rack, along with other effects.
gudluck mate.

hmm would u be able to hook up the eq so it is both pre and post amp?

it does have a nice clean sound but there is no overdriven sound i could make a bypass so that when its no overdriven it still has the same old sound. Dont really want an EQ but old_toad can you explan the resistance pad thing for me please?
