The Tone City All Spark is a mini clean boost pedal built on what the maker calls a Classic A JFET design. It provides what Tone City describes as "up to 17dB pure volume boost", with a simple one knob and two switch control layout. Depending on your amp, the maker says it will push it to the edge of break-up or just add extra volume for a solo1.
Controls
The All Spark keeps things minimal: one knob and two switches. Tone City says this layout provides a pure clean volume boost1.
| Control | What it does |
|---|---|
| Level knob | Sets the amount of volume boost, up to 17dB1 |
| Bright switch | "gives you that extra bit of upper mid-range bite, something that you would want when playing lead pa[rts]"1 |
| Fat switch | "enhances the lower frequencies, letting you improve the bass response of your amplifier."1 |
The two switches work in opposite directions tonally: bright leans on the upper mids for cutting through, while fat leans on the lows to firm up the amp's bass response1.
How it fits a board
As a clean boost, the All Spark sits apart from pedals that shape gain themselves. It is not an overdrive, distortion or fuzz: the maker describes it as a low-gain pedal providing pure clean volume. Its stated use is either pushing an amp toward break-up or lifting volume for solos1. If you want a pedal that generates its own dirt, Tone City's range includes drives such as the Tone City Blues Man, while the All Spark stays in the boost lane.
Being a mini pedal at 9.4 cm long and 0.26 kg, it takes little room on a board1.
Power and specifications
The All Spark is powered by a DC 9V power supply, and Tone City lists its current draw at 3 mA1.
The maker's page specifies a DC 9V adapter and does not mention battery power. At 3 mA the draw is very light, so it sits easily on a shared supply with other pedals.
| Specification | Value |
|---|---|
| Input impedance | 500K1 |
| Output impedance | 10K1 |
| Current draw | 3 mA1 |
| Dimensions | 9.4(L) x 4.5(W) x 4.8(H) cm1 |
| Weight | 0.26 kg1 |

Questions
What does the bright switch do on the Tone City All Spark?
The bright switch adds extra upper mid-range bite, which Tone City describes as something you would want when playing lead parts, helping the guitar cut through in a mix.
What does the fat switch do on the Tone City All Spark?
The fat switch enhances the lower frequencies, letting you improve the bass response of your amplifier according to Tone City.
Does the Tone City All Spark add distortion?
No. Tone City describes it as a low-gain boost pedal providing a pure clean volume boost. Depending on your amp, it can push the amp to the edge of break-up, but the pedal itself does not generate distortion.
Is the Tone City All Spark true bypass?
Yes. Tone City lists the All Spark as true bypass, so when it is off, your guitar signal passes through without the pedal's circuit in the way.
What power supply does the Tone City All Spark need?
The All Spark is powered by a DC 9V adapter. Tone City lists its current draw at 3 mA, which is very light, though no battery option is mentioned on the maker's product page.
Is the Tone City All Spark analog?
Yes. Tone City lists the All Spark among its analog pedals.
