B. CABINET MODELS
Now let’s look at the CABINET models:
CABINET AND SPEAKER ACCURACY
There’s not much point in having incredibly accurate amp models if the
speaker cabinet models on offer aren’t of the same exacting standards. As you
may know, in real life, the output stage of a tube amp works in close harmony
with the varying impedance curve of the speaker(s) it is driving. This intimate
and vital relationship plays a major role in producing the warm, punchy sound
and pleasing feel that we all know and love. In a nutshell, modelling a speaker
cabinet is not just a case of frequency response, but is a combination of fre-
quency response, transient response (how a speaker reacts to the strength of
how a note is played), and the all-important interaction of the amps output to
the speaker’s impedance curve. In addition, other vitally important factors that
have to be taken into account when modelling a cabinet are the actual physical
dimensions of the enclosure (cabinet), the unique tonality of said enclosure
(which will be affected by both the type and thickness of the wood it is made of)
and whether it boasts an open, semi-open or closed-back design. Special cir-
cuitry and unique modelling technology ensures that all of these factors are
well taken care of in the cabinet models built into your ToneLabSE.
1. TWEED 1X8 (TWD 1X8)
The 8-inch 3.2-ohm Alnico speaker in this cabinet model is the one built into a sim-
ple amp with a 6V6 output valve. You’ve no doubt heard the sound of this amp, but
you might not have noticed what kind of amp it really is. Although you wouldn’t
guess from the size of the speaker itself, the sound has an amazingly broad range.
The lows are deep and warm, and the highs are clean and sparkling, yet it does
not have that irritating sound typical of the 8-inch speakers often used for guitar.
2. TWEED 1X12 (TWD 1X12)
This speaker is the other half of our Tweed 1x12 Amp model. As the name sug-
gests it is a single 12" speaker, uses an Alnico magnet and made in the USA by
one of the US’s revered names in vintage loudspeakers.
3. TWEED 4X10 (TWD 4X10)
Keeping with the US made Alnico magnet speakers, this cabinet partnered our
TWEED 4x10 modelled amp. It is an open backed cab using four 10" 8 Ohm
speakers, wired in parallel for a total of 2 Ohms impedance. Although originally
intended for bass guitar, this speaker rocks for many different styles.
4. BLACK 2X10 (BLK 2X10)
Although we did not model the amp that goes exactly with this cabinet, we loved
the tone of this mid-60s Fullerton, California made open backed 2x10" ceramic
magnet (of US origin) 35 Watt combo. So here it is. Great for blues, jazz and coun-
try. As with all cabinet models it can be mixed and matched with any amp model to
