The 4-4-0 Studio is a 2W, push-pull amplifier with a single channel
preamp. This amp is very responsive to the player and cleans up
will by just backing off on the guitar's volume. As with the
other Studio projects, should this amplifier be coupled to one of our 1
x 12" cabinets loaded with an efficent 100dB or better speaker, and
then cranked to 10, it will make
your ears ring.
This project is intended for those who have built amps before.
The circuitry, while deceptively simple, yeilds an amp that is at the
threshold of stability, and as such, it is very sensitive to things such as
component choice and wire placement.
Tone goes from sparkling clean, to smoothly overdriven, to
semi-saturated distortion, depending on pick attack and guitar volume
setup. Responds very well to common pedals yet still and retains your
guitars tone.

3 stage hi-gain 12ax7 based preamp.

4-4-0 ~ Studio basic kit
The 2W 4-4-0
Studio
kit has everything
you need except a soldering iron and solder to build this amp in the
box. Upgrade and option prices apply only at the time of kit
purchase.
All shipping is
via US Postal Service Priority Mail. I use USPS "flat-rate" boxes
to minimize your shipping costs when I can.
Deliveries to the continental US usually take 2-3
days, International shipments take 6-10 days. I fill out custom
forms for all overseas shipments and put the actual value of the kits
on them. The buyer is responsible for any customs/import duties
or fees charged by the destination country.
Generally, it is much more expensive to ship the
kits with a chassis than it is to aquire one locally due to "oversize"
shipping costs. Therefore, kits shipping overseas do notinclude a chassis.
Continental US: $26.00
International: $55.00
