Three of these four finalists include an expression pedal. HX Stomp needs an external pedal when continuous foot control is part of the set.

Our pick
Start with BOSS GX-100 when direct foot control and a compatible switching amp are central to the rehearsal rig. ME-90 suits battery-powered practice that moves rooms. Wired POD Go puts expression and eight switches together when its four user effect slots fit the music. HX Stomp makes more sense inside a board that already supplies the controls. Check the whole setup, including the return to headphones.
GX-100 combines built-in expression, four numbered memory switches, a movable effects loop and dedicated AMP CTL for a compatible amplifier. It fits a prepared live rig that also records and practices through headphones at home. Verify the amp switching system and output destination. Its single loop and DSP limits still apply, and wireless phone playback needs optional BT-DUAL. The AC adapter is included.
Choose a guitar processor around the amp, pedals and controls you already use. Check the complete rehearsal bag and what changes when headphones come out.

What matters in practice
Choose the processor after planning one real song, both listening destinations and the gear that stays in the bag.
A small processor can still need an expression pedal, another switch, extra cables and places to secure them. GX-100, ME-90 and POD Go include expression. HX Stomp leaves it external and starts with three switches. List the actions needed during a real song, including banks, tuning and mode changes. HX Stomp is a sensible addition when the existing board supplies those controls. For a first rig, an integrated floorboard can avoid separate purchases. No bare-unit dimension proves which complete setup is smaller.
GX-100 AMP CTL changes a compatible amplifier’s channel. It does not carry guitar audio. POD Go Amp Out carries audio, with an optional tap before Cab/IR that also excludes every effect placed after that block. A delay arranged later in the chain can therefore disappear from the real amp feed. Decide whether the problem is switching the amp, supplying it with audio, or doing both. Confirm the amplifier’s switching requirements and input or return connection. A matching plug cannot settle those questions.
A favorite pedal can stay in the effects loop for rehearsal, then collide with the evening backing-track plan. HX Stomp and POD Go can use their return connections as AUX, which gives those sockets a different job. GX-100 and ME-90 offer optional BT-DUAL for incoming phone audio, leaving their loop connections available. A compatible computer playing through USB can be another route when it is already at the practice desk. On POD Go, also restore Return Type after AUX practice. If Aux In remains selected, enabling FX Loop mutes the other inputs while the phone track continues. Include the reset and required adapter in the purchase plan. Incoming Bluetooth does not promise wireless guitar headphones.
An amp, a mixer and headphones can need different destination settings. ME-90 requires LINE for headphones or a mixer. HX Stomp can give its volume knob only to headphones, but that leaves the main outputs at unity. POD Go keeps its main outputs stereo when headphones are connected, even with only the left main output plugged in. Check connected speakers and the required mono or stereo route before playing. None of these details supports assuming that inserting headphones automatically silences the rest of the rig.
Save the edited sound before packing up. GX-100 loses unwritten memory edits when changing memory or powering off. ME-90 can recall values that do not match the physical knobs, and its default immediate knob response can be changed to pickup behavior. A shared board needs an agreed starting memory and a fresh master-level check, even when the sound was saved. If practice often happens away from an outlet, ME-90’s AA operation is useful, with batteries to maintain and its mains adapter sold separately.
4 options
BOSS, GX-100
Useful when rehearsal needs four sounds under separate numbered switches and a retained amplifier should change channel with them. The dedicated AMP CTL connection can handle a compatible amp, while the single effects loop can move within the programmed chain. USB recording and a built-in expression pedal also cover home practice. Plan the full setup before buying: it uses mains power, wireless phone tracks need BT-DUAL, and the extra controls do not add a second effects loop.
Winner whenGX-100 combines built-in expression, four numbered memory switches, a movable effects loop and dedicated AMP CTL for a compatible amplifier. It fits a prepared live rig that also records and practices through headphones at home. Verify the amp switching system and output destination. Its single loop and DSP limits still apply, and wireless phone playback needs optional BT-DUAL. The AC adapter is included.
AMP CTL needs a compatible amp and cable. Wireless phone playback needs optional BT-DUAL.
BOSS, ME-90
Suits practice that moves between rooms or lessons, with four included AA batteries and an expression pedal already onboard. Manual mode gives effect groups their own foot controls, while memory mode recalls prepared sounds. Sharing those sounds needs care because stored values can differ from the knob positions, with pickup behavior optional. The board also records over USB. Budget separately for the PSA mains adapter and BT-DUAL if regular wall power and wireless phone tracks are part of the routine.
Choose instead whenBattery-powered lessons and direct effect-group switches matter more than a freely arranged chain or dedicated amp control. Four AA batteries and expression are included. The mains adapter and BT-DUAL are separate. Its loop sits before or after the preamp, and recalled settings can differ from the knob positions.
PSA mains adapter and BT-DUAL are separate purchases.
Line 6, POD Go
A self-contained floorboard for lessons, rehearsal and computer recording when a built-in expression pedal and direct switches matter more than a freely allocated effects chain. The selected model is wired POD Go. Its dedicated Amp Out can keep cabinet simulation away from a real amp, but Pre Cab/IR also removes every block placed after the cabinet from that output. Plan the chain before expecting the amp and headphones to hear equivalent effects.
Choose instead whenOne floorboard should contain expression and eight switches, and the sound fits four user effect slots. The selected model is wired POD Go. Pre Cab/IR Amp Out excludes the cabinet and all later effects, so check the chain before using an amp and direct output together. AUX also takes over the loop return.
Pre Cab/IR Amp Out omits the cabinet and all later blocks.

Line 6, HX Stomp
Fits a player keeping favorite pedals and wanting amp modeling, effects and a computer interface in the remaining board space. The eight-block engine also supports separate processed and dry recording paths. Three footswitches are the practical limit to plan around. Adding expression or switches can enlarge the complete rig, and using the returns for a phone backing track takes them away from external effects.
Choose instead whenAn existing board already has suitable expression and switching, leaving a small space for processing. Three onboard switches and eight DSP-limited blocks must cover the plan. External controls add to the packed rig, AUX shares the return sockets, and Phones-only volume leaves main outputs at unity.
