The HGTA20 features 3x ECC83 and two EL84 valves and is cathode biased whereas the HGTA40

features 3 X ECC83 and 2X EL34 valves and is xed bias. Output powers are 20W and 40W

RMS respectively into 8 and 16 ohms. Both ampliers feature a dedicated clean channel (1)

comprising of a volume control with Bass and Treble EQ controls, followed by a drive channel

that is further split into two sub channels (2 and3).

Channels 2 and 3 have a gain control for each of which channel 2 is a lower overall gain than 3,

and the controls are cascaded, therefore the gain for channel 3 starts from wherever channel 2

gain is set.

Following on from the gain controls are the shared EQ controls comprising of contour, bass,

middle, treble, overall reverb and nally masters 2 and 3.

Masters 2 and 3 change in sync with gain 2 and 3.

This means that a crunch tone can be set up on channel 2 and then by switching to channel

three can be either overdriven further by increasing the gain control on channel 3 or simply be

made louder by increasing the master for channel 3.

The tted reverb is a DIGILOG by Belton, generally acknowledged to be one of the best digital

reverbs available and is global (ie applies to all channels).

Rear panel features include jacks for speaker connections at 8R and 16R and the 2 way footswitch

for channel selection.

A buered eects loop is also tted with a level control and two recording out jacks which have

a tailored response to emulate a 412 cabinet. One of these is a “live”socket which enables the

amplier to still power the speaker, whilst the other is “dead” and mutes the amplier for silent

recording.

Finally located on the front panel are the two push switches that change between channels

1-2 and 2-3 (note that these switches need to out for the footswitch to work if connected).

out of the box

Now that you have your amplier unpacked it’s time to get straight into using it so begin by

following these simple instructions:

Before using set all the EQ controls to 12 o’clock and all the volume, master and reverb controls

to zero, make sure the two push buttons are out (ie in the o position ) and that the speaker is

connected to the amplier, next switch the amplier on, (the push buttons should now have a

blue halo round them), allow the amplier to warm up for a minute and plug in your guitar.

Begin by advancing the volume control on channel 1 to a level that is comfortable and play

away, test the bass and treble controls and set to a tone you like, skipping now to the other side

of the front panel reverb can be added.

Next turn the gain control on channel 2 up to 12 o’clock and push in the channel 1-2 button,

a small red indicator will illuminate next to the switch, whilst playing gently turn the master

2 knob until you reach a volume level comparable with the clean tone you already have. By

adjusting gain 1 more or less crunch can be dialled in, any adjustment at the gain end will

require adjustment at the master end. Once you have these two channels balanced move onto

channel 3.

Activating the second push button brings in channel 3, with the gain set at 12 o’clock adjust the

master for the desired volume level.

At this point it’s worth experimenting with the contour and EQ controls to “get your sound”, all

the controls are interactive so adjusting one will move the others, sounds tricky but you will nd

them very easy to use, this type of EQ has been around 60+ years.

Now plug the footswitch into the jack socket or the rear of the unit and release the channel

buttons on the front panel. These buttons will override the footswitch so they have to be OFF for

the footswitch to work!.

recording

There are two recording out sockets on the rear panel, one LIVE and one DEAD, the output from

these has a tailored repose curve to emulate a 412 cabinet, you can use either to record what

you are playing as follows:-

Using the LIVE socket allows the amplier to produce sound so you can hear what you are

playing and you will still have the interaction between the amplier and your instrument.

The DEAD socket cuts o the amplier so you will need to monitor what you are playing

through an alternative device .**(although the amplier is not producing sound the speaker

MUST remain connected!)

effects loop

Eects send and return sockets are also tted to the rear panel, place eects within the loop and

experiment to arrive at the best settings, the level control should initially be set to minimum to

avoid overdriving the eects used.

Any eects that have an output level control will now function as an overall master volume

so carefull adjustment will be needed to get the best results, also try changing the order of

the pedals round as the position in the chain will give diering results. As a general rule drive/

distortion and wah pedals should be placed between the instrument and the amplier and only

pedals that you want to act on the whole of the sound should be placed in the loop, say chorus/

ange/echo etc.

As an example an echo pedal with several diminishing repeats placed in between the

instrument and the amp on an overdrive sound would give diminishing quantities of distortion

on each repeat ,whereas placing the pedal in the loop would give constant distortion on each

repeat. The rule here is to experiment to give you the results you are looking for.

and usually fail due to rough handling and vibration, combos use more valves than heads as a rule due

to the valves being in the same cabinet as the speaker. Many crackling noises are a direct result of a

failing valve.
