Descrption
The Sapphire V2 keeps the same circuit design of the previous one with the new master volume on the front panel which has been superbly implemented to maintain the amplifier's tonal characteristics even at very low volumes. This allows you to practice quietly without sacrificing the rich, dynamic sound that defines the "Sapphire" making it ideal for both late-night practice sessions and intimate recording environments.
You were looking for an organic connection with your guitar amp, you need to start with a great clean tone. The SAPPHIRE is a single channel amp design, with bold and full-bodied clean tones.
This amp sounds really open, revealing and offer a unique tonal breath. You will feel the sound on your fingertips!
Tone stack allow you to adjust the three treble middle bass pots for a great deal of flexibility when dialling in.
Most of the tone stack tend to have a cut in the mids so we created a setting called « rough » this pot allows you to minimize the effect of the tone stack.
What makes this amp special is that the rough pot will cause the tone stack to have less and less effect as the rough pot will make the mids level up till you have a completely flat tone stack which will also help the amp to crank.
The rough pot is a “push pull” switch that allows you to pull to totally defeat the tone stack and the amp will be more aggressive, distorted and louder.
One of the amp’s qualities is also the tube driven reverb circuit.
The effect is full, deep and we tune the desired level of the reverb effect by ear while testing the amp before delivery.
The amp is equipped with a bunch of switches that allows you to experiment with different configuration such as :
High or Low B+
Hifi mode 20% and 40%
Different Negative feedback values
New Rotary Switch 3 presets

High- and low-tension switch, offers you to choose between two main B+ supply tension as High will be the normal tension and low will give about 50 volts less on the anode of the power tube and center tap of the output transformer as also less tension to the pre amp tubes.
With this switch you can travel through sound that is less aggressive, smoother, sweeter or growling cleans straight in to your face, tight and lots of dynamics…
and even brighter and sparkling if you use the “push pull” switch hidden on the volume pot.
We also implement a negative feedback switch that allows you to have 3 different feedback as Low, High and Normal.
We decided to use this mod since the Fender always had different values of the resistors on the feedback line due to the different speakers impedance value, so you would see the same circuit with different value because speakers would be 2, 4 or 8 ohms.
We thought let’s try this and see if we feel that the difference is interesting enough to make us implement a switch… and it was!
So we did it, it is really interesting to mess around with the switch …
Rotary Switch 3 positions
This new feature allows you to have 4 different presets. By this
switch you will have the possibility to have of course the Sapphire
position and 3 other presets which are :
- Blackface (Same as Vintage American standard Amps)
- Sapphire
- SRV (Diaz Mod)
PENTHODE/Hifi Mode
The second rocker switch offers a choice between pentode and hi-fi (ultra-linear) operation. In the pentode setting, the amplifier operates in a traditional tube configuration, delivering the warm, saturated tones that guitarists love. The hi-fi setting, adjustable between 20% to 40%, provides a cleaner, more linear response with reduced saturation, giving the amplifier a more precise and controlled sound suitable for various musical applications. This hi-fi setting is particularly suited for achieving the clear, articulate tones associated with Stevie Ray Vaughan when he played through Dumble amps.
Digital Bias displays
The "Sapphire V2" includes an adjustable digital bias feature, giving you precise control over the tonal characteristics and response of the amplifier. Fine-tune the bias to achieve your perfect sound, from tight and focused to warm and dynamic, making it ideal for replicating the expressive and dynamic tones of Philip Sayce and SRV.
HIGH/LOW SWITCH
Negative Feedback
So remember that this amp has been created with the tweaking guitarists in mind. The once that want to experience the quest of the perfect tone for him/her ….We all know how
subjective tone can be, let alone the fact that we're all playing vastly different gear and styles.
