Reckless 'tube-amp like' tone...
but so much more versatility!

Although based on a classic 1950s amplifier, 5E3-EXTRA is not quite as simple as it may first look!  It has a number of features which can be extremely useful, when considered along with ‘where’ they are strategically placed in it’s circuitry.  Therefore, this page is very important to the player in order to get the very best out of 5E3-EXTRA.  Certainly, the fact that 5E3-EXTRA is solid state, makes these features possible and versatile additions.

Input: Where guitars and electronics meet.  It’s designed to have a 1M Ohms impedance (Z) and 150pF input capacitance, exactly like ‘good’ ECC83 or 12AX7 tubes do, so your tone is guaranteed to have the same level of sparkle and warmth.

VOLUME: Located near the amplifier’s input - It regulates the gain of the input section and is suitable for matching widely varying modern guitar pickups to the amp for the absolute ‘highest clean headroom’ sounds. 

It can also be used to provide various amounts of ‘front-end’ distortion too.  This ‘front-end’ distortion’s character can be modified by the TONE control. 5E3-EXTRA has two types of built in distortion available. The second is the 7W alternative described later.

MASTER (Volume): Towards the output of the preamp, post tone control.  It is used to set up the output level of the amplifier according to the sound that has been set with the other controls.

TONE: Situated post ‘front-end’ distortion.  A single knob tone control which boosts and cuts the high frequencies only - by about ±10dB @ 5kHz.  Unlike the 2 & 3 band ‘mid-cut’ EQs used in classic 1960s American & British amps, this circuit is able to provide a ‘flat’ response when set to around 7 on the dial.  There is ‘no mid cut’ at any setting.
This is where the musician’s fabled ‘6V6/EL84 tone’ or ‘tweed tone’ description emanates from… and where 5E3-EXTRA’s clean tonal character is created.

FAT: This is placed pre-distortion (VOLUME control) and can be used to boost or cut the bass signal prior to distortion.  This helps to match high bass output pickups to the amp better.  Or, if required, to give its ‘front-end’ distortion sound much more ‘low end rumble’ for classic style ‘slide’ blues sounds, or just use it creatively.

PWR (HI/7W): Situated post MASTER volume.  Switching it to 7W limits the output power to about 7 Watts.  Its distortion is very ‘even-harmonic’ in tone.  It can be heard to ‘slip’ into saturation without any harshness.  Unlike the ‘front-end’ distortion, this alternative 7W distortion’s tone is completely unaffected by the TONE control’s settings.  It’s for those who really like the renowned 5E3 early distortion sound! (7W is much too loud for home use!)

Designed As A Pedal Platform amp: From the start, our design process built in 'pedal ability'. In today's world, pedals are an essential part of live music creation... it just had to do it!

Optional FX LOOP: This, if fitted to your amp, is located between the preamp and RetroTone:22™ or RetroTone:45™ power amp.  The FX SEND has a 1.6k Ohms output Z which suits it to driving professional studio FX units with typical 10k Ohms input Z (tube FX LOOPS cannot do this).  The FX RETURN has a 1M Ohm input impedance to avoid loading the output circuits of some ’iffy’ FX pedals.

Optional DI OUT (G12T): When fitted, is driven from the FX LOOP output so that all effects being used in the FX LOOP can be captured in any recording or sound reinforcement activity.  Incorporates our G12T speaker simulation used by The Hellecasters.  Output impedance: about 1.6k Ohms.  5E3-EXTRA’s internal speaker can be safely silenced by plugging an ‘empty’ jack plug into the EXT SPEAKER socket. 

RetroTone™ Power Amp: RetroTone™ is SESSION’s modern analogue solid state power amp design, which is able to provide our amps with all the chime, warmth and dynamics guitarists expect from their guitar amps. They are as loud as any similarly rated tube amp... confirmed by our customers!

Toroidal 'Humbucking' power transformer - for 70% less hum radiation than any tube amp! Perfect for all single coil pickup, especially P-90, equipped guitars! Stand nearer to your amp and pickup far less hum!

5E3-EXTRA™ is your ‘Stairway To Heaven’

Early British 'Two Eyes' R'n'R Tones

John Bell1

Sound Samples
John Bell - Reef Break
John Bell - Man Of Mystery
Recorded at The Shadders, Emsworth using: EX22-110 amp

Demoing these very old sounds is vital in showing that SESSION's solid state guitar amps are capable of true vintage tones! The sounds modern players pay a premium for when buying amps of that era. But it's here for a lot less!

Tone ability from one extreme
to another! Top players try instruments from all eras and adapt them to create their 'trademark tone'. 5E3-EXTRA can provide great rhythm tone too

Power Amp Pushing

You can even 'push' the power amp for 'on-the-edge power-tube-like' distortion! Although, better to just switch in its 7W power limiting for a more controllable experience at smaller gigs volumes

If you're a jazz guitarist, you'll love its 'sweet mid range' and 'on-the-edge' tones, especially with semi-acoustic cello style guitars. As Nigel Price found - Voted Britains top jazz guitarist

Got A Spare
Fender Blues Junior® Cabinet?

If you've upgraded your Fender Blues Junior® into a larger or better built cabinet, then you'll be left with an empty cabinet!

Install a 5E3-EXTRA™ chassis into it... it will be a perfect fit and you'll probably find it's much sweeter sounding than the original BJr tube based chassis!

One guy did this, and then put the 5E3-EXTRA™ into the upgrade cab instead!


As A Powered Speaker Cabinet

Playing via your selected multi-fx preamp directly into the FX RETURN bypasses everything else, so 5E3-EXTRA will NOT colour the tone in any way... apart from the tone of the speaker fitted. You'll need two 5E3-EXTRA amps for real stereo reproduction

5E3-EXTRA’s RetroTone™ power amps are designed to add the warmth and chime that players usually associate only with a tube guitar amp.  But surprise, RetroTone™ will easily impart the same ‘tube amp’ vitality to your modeller's tone as well.

All these uses and vintage stage appearance too!


Chassis Dimensions

EX22 & EX45 - its mounting locations enable it to fit directly into a Blues Junior® cabinet - 415W x 160D x 65H mm (inc 15mm side mounting lugs) - OK with standard BJr speaker in place.

Chassis customers - Please check your intended speaker will fit before ordering an EX22 or EX45 chassis! The maximum speaker depth must not exceed 123mm!

RetroTone Logo

What does RetroTone™ do?

As many players know, there is a difference in tone between solid state (SS) and tube amps. It is heard as a low end warmth with a sweet high-end presence. This favoured tonality is created by any tube amp's output transformer interacting with the speaker(s)

Session's RetroTone™ power amps also interact with the speakers, like a tube amp does, to provide you with that same Class AB characteristic tone

Anyone wanting old school tone, light weight and reliability should take SESSION's RetroTone™ equipped amps very seriously!  RetroTone™ is 'the cat’s whiskers' for achieving 'that' tone and volume without tube amp expense, hassle & weight

RetroTone™ is a protected name
