Main trade-off
BOSS GT-1000CORE
Headphones share an output connection, and using SEND sockets as SUB outputs consumes their loop roles.
Head-to-head
Choose GT-1000CORE when compatible amp-channel control or deliberately linked effect settings would simplify the existing rig. Amp control consumes one CTL/EXP socket, expression is external and headphones require R/MONO disconnected. Choose HX Stomp when leaving the main output wiring in place and keeping existing presets unchanged after Favorite edits matter more. It has no dedicated relay amp-control output, needs external expression and retains an eight-block DSP-limited chain. Its Phones-only volume setting leaves main outputs at unity.
Before you choose
A player keeping a two-channel amplifier may want one foot action to change both the processor and the amp. CORE can use CTL4,5/EXP2 for compatible amp control, leaving its other CTL/EXP socket to cover another assigned control. HX Stomp has MIDI and a shared expression/footswitch input, but no dedicated relay amp-control output. Choose CORE when that documented connection matches the actual amplifier and removes its separate switching task. If a working MIDI or amp-foot-control arrangement is already present, check it before paying for another route. Neither unit includes an expression pedal.
What this is based on
A retained switching amp and hands occupied by playing crossed with socket direction and competing uses. This does not establish universal amplifier compatibility or promise that an unspecified MIDI adapter will work.

Main trade-off
The connection list has no dedicated relay amp-control output. External expression and additional foot control also share one jack.

GT-1000CORE vs HX Stomp for an existing pedalboard. Check amp switching, the return to headphones and whether changing a favorite effect alters other presets.
Both are three-switch processors that can add modeling, effects and USB recording to a board the buyer already owns. Neither has a built-in expression pedal. Their strongest differences appear in the surrounding amp controls, headphone wiring and management of reused sounds.
Winner by situation
CORE can assign one CTL/EXP socket to amp control. Verify the exact electrical requirements and cable.
HX Stomp has separate PHONES. Its output-volume settings still need a speaker-level check.
CORE STOMPBOX links support that plan. HX Favorites need reloading in the presets that should change.
HX Stomp preserves those presets automatically. CORE can also isolate edits by using copied rather than linked settings.

If the board returns home still wired to two output cables, CORE needs a specific change before headphones: connect them to L/PHONES and leave R/MONO empty. HX Stomp has a separate headphone socket, so that particular main-output disconnection is unnecessary. That makes HX Stomp worth considering when preserving the board wiring matters. It does not make the speakers silent automatically. With Volume Controls set to Phones, its main outputs remain at unity, so turn down or mute connected speakers separately. CORE remains reasonable when the normal pack-up routine already removes the output cables.
An already wired rehearsal board reused for headphone practice crossed with explicit connection instructions and volume behavior. The inference concerns cable handling, with no claim of automatic output muting or measured setup-time savings.
After rehearsal, a player may refine one drive effect that appears in several song patches. CORE can link those patches to the same STOMPBOX, so changing it updates the shared settings together. HX Stomp Favorites behave differently: overwriting the saved Favorite leaves existing presets unchanged until the Favorite is reloaded there. Choose CORE’s linked workflow when the whole set should follow the change. Choose the HX approach when preserving prepared songs or another player’s presets matters more. CORE also permits copying STOMPBOX settings for local edits, so linking is a deliberate choice, not an unavoidable risk.
One reused sound across several songs or users crossed with explicitly documented linked-versus-copied setting behavior. The inference concerns maintenance and accidental scope, not tone quality or guaranteed time saved.
BOSS, GT-1000CORE
Use a compatible amp-channel connection through one CTL/EXP socket while planning the remaining controls.

Line 6, HX Stomp
Keep a separate headphone connection for the return-home routine, with connected speaker levels checked separately.
Meaningful differences
| What changes | BOSS GT-1000CORE | Line 6 HX Stomp | Why it matters |
|---|---|---|---|
| Change a retained amp with the processor | CTL4,5/EXP2 can serve compatible amp control instead of external input. | External EXP/FS input and MIDI, with no dedicated relay amp-control output. | CORE may take over the amp footswitch job, but the exact amp and cable decide compatibility. |
| Return to headphones with the board wired | Use L/PHONES with nothing connected to R/MONO. | Separate PHONES. Phones-only volume leaves main outputs at unity. | HX Stomp avoids that specific output unplugging step, but speakers still need deliberate level control. |
| Refine a sound used across several songs | Linked STOMPBOX settings are common to all patches using them. Copying allows local edits. | Overwriting a Favorite leaves existing presets unchanged until it is reloaded. | Choose whether one tweak should travel across the set or stay out of prepared presets. |
| Reuse the board for computer recording | Processed and dry USB routes. SUB routing depends on SEND settings. | Path A/B processed and Main/Return dry USB paths, with defined channel assignments. | Both record over USB. Match channels to the actual cable plan instead of choosing by channel count alone. |
What you give up
Recommendation switch
Choose BOSS GT-1000CORE. CORE provides those routes, provided its shared sockets and headphone unplugging requirement fit the routine.
Choose Line 6 HX Stomp. HX Stomp fits that handoff, with external expression, DSP and main-output-volume qualifications retained.
What matters in practice
CORE can take over a compatible amp-control job, while HX Stomp provides a separate headphone connection and keeps Favorite updates from changing existing presets.
