Tech Help - Projects Page / mudbunny bass mid pot or switch
« on: April 29, 2016, 04:57:51 AM »
Hi Guys!

Been away for a while... i will share on build reports some jobs :)

I am building a mudbunny for a bass player and i want to add a mid pot or a switch offering more control over the mids.

I read in some post that some previous versions of mudbunny ad the mid pot... feature that on the newest version is omitted.

Any suggestions?

Thanks

Build Reports / on board mini boost
« on: August 01, 2014, 05:55:00 AM »
not a stompbox... but a nice one to share!

The idea was to install a clean boost on a guitar... not my guitar hehhe

but the end result is very god and i will try it on my strat (maybe not a clean version but a dirtier one)

I grab the circuit from the web, super simple...and small



end result

Build Reports / chasm reverb
« on: July 30, 2014, 07:58:13 AM »
and... lol.... another!

Chasm reverb from dead astronaut

Not a new build.. but i think i didn't share it on the forum.

More an ambiance box but on lower settings it gives a smooth reverb! the oscillator is a nice feature

this a buffered effect but it is placed on the end of the chain so that is not a big problem for me!

combined with a delay and OMG

the face plate didn't came out very well (old and cheap pcb boards that i bought in local shop) but... ;) it works right?!

some pics:

the off board wiring is a PITA




near to my egnater


and near to my relic amp davoli

Build Reports / tap delay - photos and demo
« on: July 29, 2014, 06:04:43 PM »
And another one!

This one is a sea urchin with a tap tempo kit from uk electronics

second unit that i build and my friend want this one to have a jack to plug is external tap switch

The first unit that i build i notice that the blink rate of the tap led was out of the time but this second one (and according to the manufacturer) as improved a lot...

this is not a digital delay so when you tap the new tempo you can year the adjustment of the time but who cares!!! i have a sea urchin on my pedal board with modulation but will have to build a new one for me with this kit... but on a double parallel delay! yeaaaa!!!

The kit it self is very cheap.. i paid with the momentary switch 13Euros!

but some pics and demo

Build Reports / G Comp
« on: June 07, 2014, 07:27:30 PM »
Hey guys

Been away for a while...but still making some magic boxes lol

This one is a Ross compressor combined with a mxr noise gate. Internal chain is comp > noise gate
The noise gate and Ross is taken from tonepad. The Ross as some mods taken from fuzz central, one of the mods is the recovery switch, and it was a clean build... Can't say the same thing about the gate... It was a big trouble to make it work properly... But after changing a few things and tweaking it... Mission accomplished

The inside space was a challenge... The Ross PCB didn't help a lot... But job done

That is the second compressor model that I built... The first was a Demeter compulator and now the Ross... Honestly?? Compulator is a winner compared to the Ross

Tech Help - Projects Page / help identifying a part
« on: April 13, 2014, 01:51:52 PM »
hey guys

a friend of mine gave me an amazing surprise! An old davoli amp from 1973
its a 200wts tube amp.... and hehhe its partial working!

it uses 4xEL504 a EL80 and a ECC84
2 channels, a small reverb tank, tremolo and gain... its a beauty!!

some pics of one that i found on the web (the amp part)





this a similar one


I already found problems on some caps (filtering) and a few more things to change....

so i found the schematic of the effects/Eq/etc and i cant identify a component

its a box shape with some comps inside (resistors, caps)  and covered with some type of resin

from the schematic can anyone tell what those are?

this a photo not of my unit but it shows the parts....

Tech Help - Projects Page / Pt2399 analogue and digital grounding
« on: March 24, 2014, 06:57:02 AM »
Hi

I installing a tap tempo kit on a sea urchin
I bought the kit from UK electronics..nice price when compared with the tap chip

My doubt rest in the time pot and the analogue and digital ground of the PT (pin 3 and 4 I think...)

The original design grounds the time pot to the grounds of the PT

The kit don't... It grounds the pot just to the pcb

It works ok but I'm earing more noise than the usual (time with low settings)

Should I connect the pot to the A/D of the PT?

Thanks

I never had seen a board with all the connections indicated just by numbers... no in no out... just 1 2 3 .... but ok...
He wanted a faceplate in copper and i have to admit that is a very lovely finish!!
