MODE FOUR Front Panel Features - see panel page 70

ENGLISH

From the very start, the MODE FOUR was created with the professional guitarist in mind. To this end it boasts a host of carefully thought out features that have been designed to give you, the player, the ultimate in professional flexibility and control. These include:

■Two independent, footswitchable amplifiers – AMP 1 and AMP 2.

■Each amp type offers two footswitchable modes, giving you four in total: CLEAN, CRUNCH, OD1 & OD2.

■Each AMP has separate controls for GAIN, VOLUME, BASS, MIDDLE and TREBLE.

■Each AMP has a front panel SCOOP switch.

■AMP 2 has a three-way TONE MATRIX control.

■Footswitchable, built-in Digital Reverb with separate REVERB controls for AMP 1 and AMP 2.

■A Parallel / Series FX Loop with individual FX LEVEL controls for AMP 1 and AMP 2.

■A footswitchable SOLO LEVEL control.

■Master controls for RESONANCE, PRESENCE and VOLUME.

■The power stage is fan cooled to ensure reliable and efficient operation.

■A TUNER OUT jack with a front panel TUNER MUTE switch for ‘silent’ tuning between songs.

■XLR and 1/4" jack EMULATED LINE OUTPUTS.

■LOAD PROTECTION CIRCUITRY.

■6-way LED footcontroller supplied that controls CLEAN, CRUNCH, OD1, OD2, SOLO and REVERB.

level may be experienced when switching between these modes, especially at extreme settings.

The diagram below shows the 'Sweet Spot' area of the AMP 1 GAIN Control where the levels of CLEAN and CRUNCH are well balanced.

GAIN CONTROL 'SWEET SPOT'

(CLEAN & CRUNCH balanced)

CRUNCH mode			CLEAN mode
louder than			louder than
CLEAN	0	10	CRUNCH

Obviously, when using GAIN settings on either side of this ‘sweet spot’, if you switch between AMP 1’s CLEAN and CRUNCH modes, you’re going to have to compensate for

7. MIDDLE Control

This controls the all-important mid-range of your sound. Higher settings will make your guitar sound fatter and fuller. Conversely, lower settings will reduce the mids in your sound, giving you a more aggressive, ‘scooped’ sound.

8. SCOOP Switch

This control has been specifically fine-tuned to give the most crushing mid ‘scoop’ sound imaginable. By reconfiguring the entire post-EQ voicing of AMP 1, the tone becomes extremely aggressive – tight, punchy and focused with the highs and lows accentuated and the mids ‘scooped’ out.

9. REVERB Control

This controls the level of the MODE FOUR’s specially designed, built-in, digital Reverb for AMP 1.

10. TREBLE Control

ENGLISH

1. INPUT Jack

Use a good quality guitar cable (i.e. one that’s screened) to plug your guitar in here. The quality of your guitar cable is particularly important in a very high gain amplifier design such as the MODE FOUR. Any fault in the cable could lead to unwanted hum, noise, or high- pitched feedback.

In common with most high gain designs and in order to avoid unwanted noise, the MODE FOUR is automatically muted when there is nothing inserted into the INPUT Jack. This means that if no guitar is plugged in, the amp will be very quiet regardless of the settings.

TONE TIP: For using a separate pre-amp with the power amp section of the MODE FOUR, see Frequently Asked Questions (page 12)

TONE TIP: Microphonic (i.e. loose) guitar pickups can lead to unwanted low-end feedback at high gain settings. If your guitar suffers from this, we would suggest you visit a qualified guitar service technician to remedy the problem so you can get the optimum performance from your MODE FOUR at all Gain settings.

AMP 1 CONTROLS

2. CLEAN Mode Select Switch

Push this switch to select the CLEAN Mode of AMP 1. When this mode is selected via the front

panel or the supplied 6-way footcontroller, the red LED within this switch will be illuminated.

3. CRUNCH Mode Select Switch

Push this switch to select the CRUNCH Mode of AMP 1. When this mode is selected via the front panel or the supplied 6-way footcontroller, the LED within this switch will light up.

4. GAIN Control

When AMP 1 is in CLEAN Mode, this control will take you from shimmering, bell-like, clean tones at low settings, to edgy, valve generated bluesy distortions at higher settings.

When CRUNCH Mode is selected you enter the hallowed world of a front-ended JCM800, which will give you classic Marshall metal and alternative rock tones. Low GAIN settings will yield the truly dynamic, touch sensitive, overdriven valve roar that made the JCM800 2203 a hard rock legend. Higher levels of GAIN give you dense, saturated tone with endless sustain and a slamming, low-end thump without losing any of that all-important note definition, even when playing complex chords.

AMP 1 GAIN CONTROL SWEET SPOT: The CLEAN and CRUNCH Modes of the MODE FOUR offer a huge degree of flexibility in terms of gain.

As the GAIN Control is shared between the CLEAN and CRUNCH Modes some change in

the resulting level differences with your guitar’s volume control &/or pickup selection.

TONE TIP: At low CRUNCH settings, ballsy crunch can be transformed into wonderfully rich clean tones by merely reducing the guitar volume control.

5. BASS Control

This controls the amount of low frequencies (bottom end) in your tone. Adjusting this control in conjunction with the RESONANCE control

(12)will drastically affect the size and tightness of your low end. The more BASS and RESONANCE you dial in, the fatter your bottom end will become.

6.VOLUME Control

This control determines how loud or quiet

AMP 1 is. This control should be used in conjunction with AMP 2’s VOLUME control (19) to set the relative levels of the two amps. Once this is done you can use the MASTER volume control (16) to set the overall output level of the amplifier.

This control determines the amount of high- end and makes your guitar’s tone brighter and more cutting as it is turned up. Adjusting the TREBLE Control will allow you to fine-tune upper-end ‘shimmer’ on your CLEAN sounds and aggressive bite on your CRUNCH – especially when used in conjunction with the PRESENCE Control (13).

TONE TIP: AMP 1’s tone network is highly interactive and altering one control can change the shape of the sound in relation to the other tone controls. Experimentation is the best way to achieve your desired sounds.

11. FX LEVEL Control

When you’re using an external effects device in the MODE FOUR’s Parallel to Series FX loop, this control adjusts the amount of the chosen effect that will be mixed in with AMP 1’s dry (uneffected) signal. Please refer to the FX Loop section on page 8 for further details.
