The Fourth Time Is The Charm For This Popular Bass Synthesizer
I began my obsession with keyboard bass by buying a Rheem Key Bass, moving to a Novation Bass Station, and finally settling on a Studio Electronics SE-1x. As a novice keyboardist, though, Iโve never given up trying to get synth bass from my pedals, usually by dialing in a combo of octave, envelope filter, chorus, harmonizer, overdrive, and wah flavors. Eventually, my quest for the perfect all-in-one synth-bass pedal led me to buy two Akai Deep Impact units in the early 2000s, and although they were far better than anything else available, I sold them because the tracking wasnโt great, and the presets werenโt consistent; Iโd program an awesome sound in rehearsal and be disappointed at the gig.
Fortunately, Andras Szalay, the original designer of the Deep Impact, has continued to refine his creation. Szalay began making the Future Impact in 2015, and his fourth iteration aims to be the go-to synth pedal for bassists who want authentic analog-style sounds without playing keyboard.

How It Sounds
The v4โs stock sounds run the spectrum from gig-ready to far-out. Among the unitโs 99 patches, I heard many classic synth sounds that made me squeal with joy, speechless with surprise, and thoughtful with possibilities. Once I plugged in, it was hard to stop playing.
The list of default sounds divides the patches between bass (1โ67), effects (68โ76), guitar (77โ85), MIDI (86โ94), and EWI (95โ99). Patches 21โ29, a numbered series called โDI emulation,โ do a good job of easing virgin ears into the Future Impactโs offerings. As I began to explore, I found that some patches were straightforward, like 85 (โGTR_Bassist_Substituteโ), which I used like an octaver. Others, like the 808-ish 36 (โO, si, tu!_Accentโ), put me on the dancefloor; yet others (like 64, โWoody Dropsโ) transported me to a space-age bachelor pad, and a handful โ including 32 (โStr_Chords_Min_Maj_Acc_Rโ), 50 (โElectronic Cuckoosโ), and 59 (โHeavensArpโ) โ sounded like theyโd be perfect for film scoring. I loved the meditation lounge that popped into my head when I played 45 (โSinging Chordsโ), and I enjoyed the more complex, layered sounds like 46 (โEnvSlideโ) and 55 (โOctave Twinklesโ). My personal faves? Patches 48 (โLowSpikeโ), 53 (โPolka_Madnessโ), 61 (โSustain Brass,โ a total song-starter), 74 (โPowerchordโ), 78 (โHighSoloโ), 86 (โBRI derivation_ATโ), and 89 (โGet A Desk!โ).
When I called up patches that seemed over the top โ like 30 (โDonโt Sync To Their Levelโ), 34 (โTwentyFirst CTโ), 62 (โTwinkle Delayโ), 82 (โSynthFuzzโ), and 88 (โMen At Workโ) โ I simply adjusted the BALANCE knob so that I was mainly hearing my bass with just a touch of freaky effect. I wasnโt even sure what to do with 17 (โMoneyDrumAndBassโ) and the scary-ish 52 (โSpookyโ), but Iโm sure Iโd find a use for them.
Some sounds, like 37 (โDelayed Intervalsโ), surprised me when I let a note sit for a second. Patch 76 (โTinyVerbโ) was a highlight of the effect patches, which also include delay, flange, filter, phaser, and a faux fretless. On a couple patches, like 87 (โI_ll Go My Own Way_ATโ), muting one note before starting another made a huge difference. Other sounds, like 47 (โMegasynthโ), cried out for a wah pedal. When I played these effects while slowly stepping on a Dunlop Cry Baby Mini Bass Wah, it brought out juicy nuances that made me wonder what other pedals might pair well with the v4.

Whatโs Hot
The Future Impact v4 is tough, lightweight (600 grams), and small (not much bigger than two Boss pedals). The layout is compact but functional, with well-placed knobs and a bright LED display for navigating presets and parameters. Tapping the PROGRAM footswitch once moves to the next preset, and tapping twice moves backward. The v4 works with any 9-volt Roland/Boss-style adapter.
The software editor provides access to every parameter, including envelope settings, LFOs, and filter types. Synth nerds will appreciate the visual interface, which makes programming much easier than menu-diving on the pedal itself.
If youโre a serious MIDI user, youโll like being able to change patches remotely via MIDI program changes, control parameters in real time using MIDI CC messages, and sync LFOs and arpeggiators to external MIDI clock sources. The Future Impact v4 also boasts a CV/gate output, which allows it to control external analog synthesizers or modular gear. It was thrilling to play the Future Impact with a MIDI controller and then use it to trigger sounds while playing bass on my SE-1x.

Whatโs Not
Certain patches can sound a bit harsh or digital, particularly when using higher-pitched tones, and some patches might need EQ to cut through in a band context. Use your EQ/preamp accordingly.
Tracking on some patches could be inconsistent when I played fast lines. Thankfully, changing the ATTACK and BALANCE settings, using a pick for definition, and making sure I was aggressively muting stray strings helped a ton. The v4 was great when I used bends and slides to mimic the expressiveness of pitch and mod wheels on a keyboard; itโs monophonic, but a few patches occasionally processed chords and double-stops.
Some folks find that the software editor can be a bit overwhelming, so if youโd rather deep-tweak things away from your computer, youโre out of luck. Also, there have been reports of occasional compatibility quirks with certain operating systems.

How It Compares
The Future Impact is more expensive than any of its nearest competitors, but it shines in ways that others donโt. The Source Audio C4 Synth lacks the Future Impactโs screen, and it requires an app for full control. The EHX Bass Mono Synth is far less tweakable, and it has fewer sounds. And the Boss SY-200 is arguably less synth-like and not as analog-ish as the four-oscillator Future Impact.
The v4 is a huge improvement on the original Deep Impact, but even compared to the first three Future Impact pedals, the v4 offers sturdier knobs plus superior tracking, MIDI, and CV/gate possibilities, as well as an upgraded software editor. (After our review went to press, Panda Audio released the Future Impact V4 VIP Edition, which puts the same features in a smaller, more pedalboard-friendly case for $50 more.)
