Hej!
Varför inte modifiera den?
Är Du osäker på att göra det själv så känner Du säker någon annan som kan göra det år dig. [;)]

http://www.stinkfoot.se/mods/ts9mod.htmTube Screamern som sådan är också designad med ett högpassfilter i klipp/distkretsen
som börjar begränsa basen redan vid 720 Hz, och de lägsta frekvenserna blir således inte
överstyrda alls. Detta är gjort för att tonen inte ska bli luddig i basen, och det är
också högpassfiltret som (tillsammans med en diskantbegränsande krets) ger TS-9 dess
karakteristiska spark i mellanregistret. Nackdelen blir att pedalen egentligen bara låter
riktigt bra på riktigt hög volym, eftersom det är först då man får ut nog med bas från den.

http://www.musicianshotline.com/archive ... r/0603.htmThe part we want to remove is the capacitor that controls the bass roll-off.
This high-pass filter is controlled by the capacitor that is located right above
wire markers 10 and 11 on the circuit board. It will generally be a yellow cap that
is marked 473. That is 0.047uF (marked "A" in the picture). We are going to replace
it with a 0.1uF capacitor. Radio Shack part number 272-1053 for the metal film type
if you want to go fancy, and 272-1069 if you want the same quality Ibanez uses, which
is fine for what we are doing here. It is the new value we are most interested in.
To increase the amount of drive or saturation this pedal can achieve while we are in
this area, change the resistor between marker 13 and 11 (just above and a little to the
left of the cap we just changed). Change this 4.7k-ohm resistor (marked "B" in the picture)
to a lower value; say 2.2k-ohm, RadioShack part number 271-1325. Better yet get an assortment
pack from them so you can experiment with lower values to get even more horsepower, err..distortion!
Now look at the other side of the IC (the chip or op-amp depending on what part of town you're from!).
There are two little can-type capacitors. They 're blue-black in color and have the markings 1uF on them
("C" in the picture). They are located between wire markers 8 and 9 and the other is between 10 and 11,
they are also marked NP on the board so that will help locate them. Replace these with Radio Shack part
number 272-1055. Whoa!!! Those are huge! Yes, take some wire and use the plastic insulation for insulation
on the legs of these large caps so that nothing touches or shorts out. Or, you can use Digi-key.com part
number P4675-ND like we use here at the shop. They fit nicely. These are changed to increase the transparency
of the pedal. This is subtle but noticeable. Like putting a new air filter on your car and thinking it drives
and handles better!
Bottom line, these changes are things that make a difference. People will notice your better tone.
Customers report to me that even the drummer in your band will notice and ask you to turn up a bit!
Say "Yumei Onkyo", Famous Sound!
