INPUTS
Two INPUTS are provided on the Cali Tweed to allow for different gain levels, pickup output levels and tone.
NORMAL is the “full strength” input and allows the full signal of your instrument to hit the first stage of the
preamp with all your guitar has to say about output. This input allows more touch sensitive transitioning
between clean and saturated sounds when the GAIN control is set above approximately 12:00, depending
on your pickup’s output strength. The higher the setting of the GAIN control, the more easily you will be able
to push the preamp into clip, and even power section (depending on wattage selected on the rotary POWER
SELECT) into saturation/overdrive.
The NORMAL input is also the brighter input and allows the maximum harmonic content from your instrument
to pass through the preamp. This will ensure the tone controls react with their full power and that gain levels
are allowed to reach their maximum. Most of the critical “Toning” during the development of the amplifier was
done using the NORMAL input, so as to ensure all gain regions and frontiers were explored and refined to their
absolute maximum potential. We suggest using the NORMAL input first and exploring the amplifier, as it will
provide the unadulterated full range of sounds possible with any given guitar.
The LOW input should be explored for maximum headroom at the input of the preamp, and/or for the absolute
cleanest (not necessarily brightest, which can often be confused for cleanest) response and character. For the
loudest, greatest headroom clean sounds use the 20-watt setting on the Multi-Watt™ rotary.
The LOW input is “padded” so that a reduced signal is presented to the first preamp tube stage. This padding
also reduces the midrange punch and brightness, so you will have to determine what is most important to you,
headroom or “cut”, and choose inputs with that in mind.
More cut would actually be found with the NORMAL input, as though it may be less pristine in terms of the onset
of clip, it’s inherent punch and more active tone control string response due to the higher signal strength, may
actually sound cleaner or feel better in an ensemble. Experiment with both inputs to learn which one works
best for your application.
Just be aware that brightness (as in EQ) is often confused with headroom, clarity and even power. Brighter
sounds feel faster, cut though a dense mix more effectively, and in general, can appear as having increased
headroom. That’s partly because high frequencies reach your ear faster than low frequencies do and therefor
the feedback to your hands and ears is more immediate than with darker, warmer sounds. This can be a bit
deceiving at times though, so use your sense of feel and your ears to make the determination about which
input is best for a given application.
The LOW input and its inherent top end roll off can be nice for Jazz playing or single note solo work where
increased cleanliness and a warmer character is desired. It may take a bit to get accustomed to the less immediate,
less forward feel as compared to the NORMAL input, but there are some nice and unique sounds available using
