Resistive LoadBox

Hi Guys,

I've done a recent resistive loadbox to take along with my 12W 6v6 amp (a Supro clone) for a while. I simply cannot carry and use a real cab.

This one that I did uses a 25W 8 Ohm resistor and has a circuit for a line output and treble bleed... I take the signal from this "hot" box and do some cabin simulation with IR's on the computer. I've done the following with my 98 MIA Blues Jr. and 76 Deluxe (no pedals; the master at the amp is 12 all the way up, volume is like 6, bass/mids/treble are all maxed). The cab sim, comp etc. are done via the soundcard on the computer. The cab sim is LeCab2 and RedWirez' Marshall 1960 cab with v30's; TDR comp and eq; Classic plugins' reverb and delay.



Here is the layout of the beast:

I think it is quite a usable box. It is resistive... the next step is to have 2 inductors and do a Aiken type of reactive load... But this should do for this summer.

Best,

B

Sorry... some bits of the graph is in Turkish... :D

T is Ground and S for Signal (Hot).

I did this yesterday... on a backtrack. Using my Blues Jr. and 76 Deluxe... No pedals in general, just a TS around the end.

This box works.

Re: Resistive LoadBox

Resistive loadboxes are cool, but try a reactive loadbox (with air coil) sometime... noticeable difference in tone.

Just make sure you have diodes in that reactive loadbox, so the flyback voltages don't fry your amp.

Aiken's does not have any diodes? Bipolar caps tho.

Captor is fine but it does not have the treble inductor I think... Suhr reactive load is cool but expensive and does not come with the goodies that Two Notes Captor does. I wanna do one, one of them Aiken's... hence, the question.

I don't know what the Aiken does or doesn't have... you'd have to see a circuit diagram or picture of the internals.
