The dip switches change the clipper circuit. With both down you’re
at the least compressed symmetrical setting. That just means that
both sides of the signal wave get clipped the same amount. When the
switches are up (on) it compresses more with more distortion, but
still a symmetrical clipping. You'll notice a reduction in volume
because the signal gets clipped sooner. With one switch up, and one
switch down you're clipping one side of the wave harder than the
other - asymmetrical. That's a setting that a TIM pedal doesn't have.
You wont hear a difference between which switch you have up or
down when using the pedal by itself, but if you stack it with another
pedal you might.
This is a little tricky to explain, but some pedals have asymmetrical
clipping going on. The top part of the wave will be clipped harder
than the bottom. Or another pedal might do the opposite - clip the
bottom hard, and soft clip the top. The dip switches in Timmy let you
pick which side you hard clip, so it might make it sit better with
another pedal if you have Timmy hard clip the top, while the other
pedal hard clips the bottom. That's sort of what goes on in a tube
preamp with several gain stages.
The Timmy pedal is a smaller boxed version of just the
main section of the TIM.
The Pedal is a flat/clean booster to mild crunchy overdrive effect.
It's not a high gain compressed type of lead pedal. This is more
about adding boost and distortion while keeping the punch and
dynamics of the amp. It has a main mode of operation, and a boost
mode that's meant to kick things up a bit. Also included is a post
effect series FX loop. The Timmy does not have the boost section or the FX loop.
The main mode has gain/bass/treble/volume controls. The bass
and treble controls are "cut" style controls. That means that as you
turn them clockwise they will roll off the bass and treble frequencies.
Zero (7 o'clock) is flat - no cutting of the frequencies. It seems
backwards, and it is!
The bass control is pre distortion. Most pedals roll off the low end
before you distort the signal to keep things tight and clear. A lot of low
end distortion can get real muddy real quick. But what that means is you
don't have the low end there when you need it for cleaner settings. The
bass control will allow you to keep all the low end for the cleaner sounds,
and dial it out for the good crunchy stuff.
The treble control is post distortion. Like the bass circuit most pedals
will have a preset hi end roll off to keep the pedal from being fizzy and
noisy when distorting, but you'll lose the hi frequencies for the cleaner
settings. So for cleaner settings you might have the treble on zero (7
o'clock) for all the highs, and as you turn up the distortion you would roll
back the treble to keep things smooth.
Being able to control the pre and post EQ gives you the ability to kill the
evil mid bump a lot of pedals have preset into them. You might have
them on zero for the cleaner stuff, and rolled back to something like 3
o'clock for the distortion tones. Don't be afraid to roll them all the way
The boost mode is a strange little gain/volume boost circuit. It's not
meant to be a two tone on the fly type of circuit. It's more about if the
gain cranked isn't enough you'd kick this on. The drive control on the
back of the pedal changes the gain of the clipping circuit. The tone
control effects the low end of this gain circuit at high boost levels. I
think it works best when the main mode is already set up for a nice
medium distortion. Then kick on the boost for some more hair.
There's a pull pot on the back of the pedal that changes the clipping
circuit to react faster. It will distort with lower signal levels increasing
distortion and compression. It effects both modes of the pedal. The
Timmy pedal has this function inside using two dip switches. Both
switches up (on) is equivalent to engaging the pull pot on the Tim pedal.
Both down is regular mode. The use of two switches allows an additional
position with on switch up and one switch down which sets the pedal for
