Dummy Loads to match Ohms?

    Ok, so here is my problem :)

    I have a 4 Ohm cab.. and I would like to get a Tiny Terror connected.. The Terror only allows 16 or 2x8 Ohm connection..
    From what I understand, connecting it to a 4 Ohm cabinet would damage the amp...

    Does a device exist which would take the correct load off the amp (so to speak) to allow me to use a 4 Ohm cabinet, or would i have to go out and buy a new cabinet?

    What cab are you looking to use?

    Some sort of mass loadbox I guess.

    Something like this maybe?

    Surely cheaper to jerry rig something yourself (a resistor in series seems to easy to be right :confused:) but I would wait for a tech head like Paolo to jump in and advise on that first.

    There's a couple of things you can do.

    You could add a 4 ohm load in series with the cab to present an 8 ohm load to the amp - for this you could use an attenutator or other premade load box (you're talking a couple of hundred euros), or possibly you could use a big 4 ohm resistor. The resistor won't sound great, and high wattage resistors actually aren't all that cheap.

    A much better idea, I think, would be to change the internal wiring of the cab. I would assume it's a a quad of 4 ohm speakers wired in series/parallel. If you rewire them all in series the cab will be 16 ohm.

    Yeah that's the kind of solution I was hoping might work...

    The other lazy assed solution :) was to go for a BlackHeart 5w (which has 4OHm output)... but tonally it seems way short of the Tiny Terror :( Would be interested if hearing if people have played both... (the Epiphone Valve Jr seemed to have too clean of a tone for me)
