Amp's type: Castel - all tube, 60 Watt head for solo guitars
Artist: ? Tolnai István
Band: (independent amateur)
Dátum: 24.07.2013.

Where tested (practicing room, concert, studio, shop):
at home

Instrument that used for test:
Ibanez SRDX 300, Ibanez GSR 200, Ibanez TRB 100,
Jolana Vikomt Bass (middle '70s!)

Cabinet that used for test:
self-built cabinet (1×12")

External appearance (Design):
Simply perfect. It is totally incidental, but I have triangle-shape reflex holes on my self-built cabinet. It is clearly reflecting back on the amp.

Sound (clean and distorted channels, tone, etc.):
I made a serious intentional mistake. I can tell you, I tested an amp built for guitars, but with bass... Really surprising, but this amp handling the bass guitar without any further effort. He did not really care that not a solo guitar feeds him. About the distortion: Cliff Burton (+R.I.P.) played the “For Whom The Bell Tolls” intro in my room! Totally the same sound. It was unbelievable, a real extraterrestrial experience. The selectable different output impedances feature is very useful and unique idea.

Features (Effect-loop, foot switch, etc.):
I did not try the effect-loop, 'cause I have no any pedal, but the foot-switch itself is very cool.

What kind of other amps should be build (combo, different power range, etc.):
To create a combo would be a good point both for solo- and bass guitars.
Due to the power: not necessary to increase, that's fine as it is.

...further wishlist:
- a lower power bass head (for example 100W)
- to make an obviously cheaper „base”-category amp family without any extras
  (It should not necessarily to coloring the tones with the end stage.
  For distortion, and playing with the tones many pedals available.)

Suggestions (further features, appearance, etc.):
Not related to the amplifier, but the foot switches. I'm missing a fifth switch. This is the MUTE.
another things: in case of such amps, who contains 2 end-tubes – I would assembled to the outer positions, 'cause when the 6L6 tubes warmed up, they aren't visible through the front grid.
(This is not a problem in case of an 4-tubed amp, because all 4 positions are filled.)
…and among many things this fact gives very cool face for a tube amp.
For the same reason: I would remove the caps off the little tubes.

Test Nr.2 --- Colton SP-150B SE


Cabinet that used for test:
SP-115B bass cabinet with one Eminence 15" speaker (not covered yet...)

Date: 12.11.2013.

Where tested (practicing room, concert, studio, shop):
at home

Instrument that used for test: Ibanez TRB 100

Amp's type:
Colton SP-150B SE
SE... Special Edition, the first 150W bass power plant

External appearance (Design):
Absolute family member. Earlier, I liked very much the tilted front panel of the Colton. The middle-gray painting with white labels also became a benefit of the design. The same coloured front side panel has unique difference compared to the "general".
Nun grid! - because of it I just call my sweetheart "The Confessor"!

Sound (clean and distorted channels, tone, etc.):
It has pure and beautiful sound, like other SP Amps has, especially when the signal runs through the amp "cleanly".
Compressor is switched off, like the 4 and the 6-band EQ also.
If some correction is neccessary, my way is to use the 6-band EQ only.
It gives a little hardness and more power to the sounding when all the potmeters stand in middle (0dB) position. You can see a setting in some pictures below, which shows that the mid-range lifted (only with approx. +1dB) and the highest frequency cutted with also (-1dB).

Features (Effect-loop, foot switch, etc.):
I have no any effect, Colton's foot-switch is under construction yet.

What kind of other amps should be build (combo, different power range, etc.):
My desire is fulfilled (see the previous test),
the 200W Colton's younger brother is here!
In this category, smaller than 150W is not recommended! This is good as it is.

Suggestions (further features, appearance, etc.):
The following remark is occurring on lower volume.
I feel the built-in cooler fan too loud. If I switch off the fan the hum disappears.
